Answer:

(x + 5)(x + 5)

Step-by-step explanation:

[tex]x^2+10x+25\\(x+5)(x+5)[/tex]

Answer:

(x+5)(x+5)

Step-by-step explanation:

x²+10x+25

x²+5x+5x+25    

x(x+5)+5(x+5)            

(x+5)(x+5)

Answer:

x^2 +3x

Step-by-step explanation:

The outer rectangle has an area of

A = l*w = (4x)*(x+2) = 4x^2 +8x

The inner rectangle has an area of

A = (3x+5)*x = 3x^2 +5x

Subtract the inner rectangle from the outer rectangle

Shaded area = 4x^2 +8x - ( 3x^2 +5x)

Distribute the minus sign

                       =4x^2 +8x -  3x^2 -5x

Combine like terms

                       = x^2 +3x

Answer:

x < [tex]\frac{15-3a}{a-4}[/tex]; a > 4

a < [tex]\frac{4x+15}{x+3}[/tex]

Step-by-step explanation:

ax+3a < 4x + 15

ax - 4x < 15 - 3a

x( a -4) < 15 - 3a

x < [tex]\frac{15-3a}{a-4}[/tex]

ax + 3a < 5x + 15 -x

ax + 3a < 4x + 15

a( x + 3) < 4x + 15

a < [tex]\frac{4x+15}{x+3}[/tex]

Answer:

x <  (15 - 3a) / (a - 4). ( only true if a > 4)

a < (x + 15)/x

Step-by-step explanation:

a(x + 3) < 5x + 15 - x

ax + 3a < 5x + 15 - x

ax  - 5x + x < 15 - 3a

ax - 4x < 15 - 3a

x(a - 4) < 15 - 3a

Dividing both sides by (a - 4):

x <  (15 - 3a) / (a - 4)

a < (x + 15)/x

Answer:

quadratic trinomial

Step-by-step explanation:

(8x^2 + 3x) – (12x^2 - 1)

Distribute the minus sign

8x^2+3x-12x^2+1

Combine like terms

-4x^2+3x+1

This is a quadratic since the highest power of x is 2

This is a trinomial since there are 3 terms

The x and y intercepts of a line are when [tex]y=0[/tex] and [tex]x=0[/tex] respectively.

The given equation is:

[tex]\frac xc + \frac yd = 1[/tex]

(1) Why c and d are the intercepts

We have:

[tex]\frac xc + \frac yd = 1[/tex]

Multiply through by cd

[tex]cd \times \frac xc + cd \times \frac yd = cd \times1[/tex]

[tex]dx + cy = cd[/tex]

A linear equation is represented as:

[tex]Ax + By = C[/tex]

Where:

[tex]\frac CA \to[/tex] x intercept

[tex]\frac BA \to[/tex] y intercept

So, by comparing [tex]Ax + By = C[/tex] to [tex]dx + cy = cd[/tex]

[tex]\frac CA \to d \to[/tex] The x-intercept

[tex]\frac CB \to c \to[/tex] The y-intercept

(b) How the intercepts are related to c and d?

In (a) above, we have:

[tex]\frac CA \to d \to[/tex] The x-intercept

[tex]\frac CB \to c \to[/tex] The y-intercept

When [tex]x = 0[/tex]

We have:

[tex]dx + cy = cd[/tex]

[tex]d \times 0 + cy = cd[/tex]

[tex]cy = cd[/tex]

Divide by c

[tex]y = d[/tex] ---- the y-intercept

When [tex]y = 0[/tex]

We have:

[tex]dx + cy = cd[/tex]

[tex]dx + c \times 0 = cd[/tex]

[tex]dx = cd[/tex]

Divide by d

[tex]x =d[/tex] ---- the x-intercept

Answer:

196000 tiles.

Step-by-step explanation:

The 28 m is 2800 cm. So a 28 x 28 meter square would be 2800 x 2800 centimeter square.

The tiles are 40 cm.

If you divide 40 from (2800 x 2800). (2800 x 2800) ÷40 = 196000

So 196000 tiles.

I'm not entirely sure if that's correct, but if it helps that's awesome.

Step-by-step explanation:

These following ordered pairs are on the graph:

-------------------------------

An ordered pair (x, f(x)) will be on the graph if replacing them into the equation, we get an equivalence.

-------------------------------

The equation is:

[tex]f(x) = x^2 - 1[/tex]

-------------------------------

(0,1)

Here, we test [tex]x = 0, f(x) = 1[/tex]

Replacing into the equation:

[tex]1 = 0^2 - 1[/tex]

[tex]1 = -1[/tex]

False, so not on the graph.

-------------------------------

(0,1)

Here, we test [tex]x = 1, f(x) = 0[/tex]

Replacing into the equation:

[tex]0 = 1^2 - 1[/tex]

[tex]0 = 0[/tex]

True, so on the graph.

-------------------------------

(3,5)

Here, we test [tex]x = 3, f(x) = 5[/tex]

Replacing into the equation:

[tex]5 = 3^2 - 1[/tex]

[tex]5 = 8[/tex]

False, so not on the graph.

-------------------------------

(5,24)

Here, we test [tex]x = 5, f(x) = 24[/tex]

Replacing into the equation:

[tex]24 = 5^2 - 1[/tex]

[tex]24 = 24[/tex]

True, so on the graph.

-------------------------------

(-2,3)

Here, we test [tex]x = -2, f(x) = 3[/tex]

Replacing into the equation:

[tex]3 = (-2)^2 - 1[/tex]

[tex]3 = 3[/tex]

True, so on the graph.

-------------------------------

(-4,-17)

Here, we test [tex]x = -4, f(x) = -17[/tex]

Replacing into the equation:

[tex]-17 = (-4)^2 - 1[/tex]

[tex]-17 = 15[/tex]

False, so not on the graph.

Width = 11ft

Length = 12ft

Area = 2(11(12) + 9(12) + 9(11))

Area = 678ft²

Answer:

678 ft^2.

Step-by-step explanation:

The surface area consists of 3 pairs of congruent rectangle.

= 2(9*12 + 11*12 + 9*11)

= 2 * 339

= 678.

(x + 1/x)² = x ² + 2 + 1/x ² = 10 + 2 = 12

Concept:

Here, we need to know the idea of the isosceles decomposition theorem.

The Isosceles Decomposition Theorem states that in an isosceles triangle if a line segment goes from the vertex angle to the base, the following conditions are equivalent:

In this question, the first condition that is equivalent would be useful.

Solve:

Given information

First side of the line segment (TU) = 2x + 24

Second side of the line segment (UR) = 5x - 30

Given expression deducted from the first condition of the isosceles decomposition theorem

Second side = First side

Substitute values into the expression

5x - 30 = 2x + 24

Add 30 on both sides

5x - 30 + 30 = 2x + 24 + 30

5x = 2x + 54

Subtract 2x on both sides

5x - 2x = 2x + 54 - 2x

3x = 54

Divide 3 on both sides

3x / 3 = 54 / 3

Answer:

1. 2.5% of 14000= 350

2. 27.5% of 1760= 484

Answer: x = 7°

Explanation:

We know that sum of angles of a quadilateral is = 360°

Therefore ATQ

⇒ (12x-4)+(18x+4)+(15x+10)+(5x) = 360

⇒ (12x + 18x + 15x + 5x) + (-4+4+10) = 360

⇒ 50x + 10 = 360

⇒ 50x = 360-10

⇒ 50x = 350

⇒ x = 350/50

⇒ x = 7

Therefore value of x is 7°

Step-by-step explanation:

is the answer

cos-¹(27/28)

Answer:

75 degrees

Step-by-step explanation:

law of sinus :

a/sin(A) = b/sin(B) = c/sin(C)

where the sides are always opposite to the used angles.

so,

28/sin(90) = 27/sin(angle)

28/1 = 28 = 27/sin(angle)

28×sin(angle) = 27

sin(angle) = 27/28 ≈ 0.96

angle ≈ 75 degrees
