some helps plssss i need help

Answer:

2: 4

3:32

Step-by-step explanation:

so you are first going to solve in the parentheses and then solve the exponents

Area is length x width:

4x^3y^2 x 3x^2y^3

Apply the exponent rule: a^b x a^c = a^(b+c)

4 x 3 = 12

x^3 x x^2 = x^5

y^2 x y^3 = y^5

Combine for final answer: 12x^5y^5

Answer:

false

Step-by-step explanation:

the equation x would be -1.04 or 1.03 so it would be false

Answer:

the actual answer is true

Step-by-step explanation:

Step-by-step explanation:

Hey there!

75° + 28° + angle KFG = 180°( being linear pair)

103° + angle KFG = 180°

angle KFG = 180° - 103°

Therefore, angle KFG= 77°

Now;

angle KFG + 28° +22° + X= 180°{ co-interior angle}

77°+28° + 22°+x= 180°

X = 180°-127°

Therefore, X = 53°

y == X+22°= 75° { being alternate angle}

angle KFG+x+z = 180° {sum of interior angle of triangle}

77°+53° + z = 180°

z = 180° - 130°

z= 50°

Therefore, X= 53°, y = 75° and z= 50°.

Hope it helps...

Answer:9/10

Step-by-step explanation:You find the square root for 81 and 100. Once you find the square root of 81 you get 9 and 10 for 100.You do this for all fractions.Hope this helps! :) I meant a smiley face

Answer:

[tex]\frac{9}{10}[/tex]  

I hope this helps!

Answer:

x = 9

Step-by-step explanation:

6x + 7 = -x + 70

~Subtract 7 to both sides

6x = -x + 63

~Add x to both sides

7x = 63

~Divide 7 to both sides

x = 9

Best of Luck!

use a divider to find the length of the middle line then use

Answer:

[tex]2x + 11[/tex]

Step-by-step explanation:

1) Expand by distributing terms.

[tex]2x + 6 + 5[/tex]

2) Collect like terms.

[tex]2x + (6 + 5)[/tex]

3) Simplify.

[tex]2x + 11[/tex]

The first step to do this equation is to expand.which means to solve whats inside the parentheses first. If you expand you'll get a answer of 2x + 11.

Answer:

A

Step-by-step explanation:

Answer: its more than each other

Step-by-step explanation:

Answer:

Step-by-step explanation:

Area of rectangle= Length x Width

and the given Area is a quadratic expression

A=[tex]x^{2} -4x-21[/tex]

We use the factorization method so,

we need 2 numbers that when multiplied we get -21 and when we add/subtract we get -4 so,

A=[tex]x^{2} -7x+3x-21[/tex]

now we simplify,

A=[tex]x(x-7)+3(x-7)[/tex]

A=[tex](x-7)(x+3)[/tex]

This looks familiar doesn't it, when we write the formula for the area of rectangle its

A= Length x Width and the equation here shows that

A= [tex](x-7)(x+3)[/tex]

So the expression for the length is x-7 and

the expression for the width is x+3 i think u have missed maybe some information on the question as such that the perimeter might be missing because length could be either x-7 or even x+3 same goes for width maybe someone can correct me if im wrong

Answer: y=4x+6

Step-by-step explanation: you replace the variables in the equation with the variables in the point given to find b.

Answer:

[tex]y = 4x+6[/tex]

Step-by-step explanation:

Equation of a line

The equation of a line can be written in the form:

[tex]y = mx+b[/tex]

Where m is the slope of the line and b is the y-intercept. We are given the value of m=4, thus the equation becomes:

[tex]y = 4x+b[/tex]

To find the value of b, we use the point (0,6):

[tex]6=4*0+b[/tex]

Solving:

[tex]b=6[/tex]

Thus, the equation in slope-intercept form of the required line is

[tex]\boxed{y = 4x+6}[/tex]

Answer:

The sum of two irrational numbers, in some cases, will be irrational. However, if the irrational parts of the numbers have a zero sum (cancel each other out), the sum will be rational.

v=18

v will not equal 14; it will equal 18

Answer:

(0,4)

Step-by-step explanation:

The jet travels a distance of

(960 km/h) t

after time t, while the light plane travels a distance of

(560 km/h) t

The jet is faster than the light plane, so the distance between them is

(960 km/h) t - (560 km/h) t = (400 km/h) t

so the time it takes for them to be 4560 km apart is

(400 km/h) t = 4560 km

==>  t = (4560 km) / (400 km/h)

==>  t = 11.4 h
