Step-by-step explanation:
1. Slope
2. Hypotenuse
1. A 10-foot long ladder leans against a vertical wall such that its base is 4 feet
from the bottom of the wall. Determine, to the nearest tenth of a foot, how high,
h, the ladder reaches up the wall.
Answer:
9.2
Step-by-step explanation:
follow the equation for the hypotenuse of a right triangle.
a^2+b^2=c^2
4^2+b^2=10^2
16+b^2=100
b^2=100-16
b^2=84
b=9.2
Answer:
The answer is 9.2. Hope this helps.

Answer:
d. 18x^3-27x^2y
Step-by-step explanation:
(3x)^2(2x-3y)
work out the first term
9x^2(2x-3y)
distribute
18x^3-27x^2y
Answer:
(d.) [tex]18x^3-27x^2y[/tex]
Step-by-step explanation:
When given the following equation,
[tex](3x)^2(2x-3y)[/tex]
Systematically perform the operations. Use the order of operations, the order of operations states the following,
1. Parenthesis
2. Exponents/ radicals
3. Multiplication/ Division
4. Addition/ Subtraction
Remember, when performing an exponential operation, one multiplies the base by itself the number of times the exponent indicates. In the given equation, perform the exponent by multiplying the base (3x) by itself twice.
[tex](3x)^2(2x-3y)\\\\(3x)(3x)(2x-3y)\\\\(9x^2)(2x-3y)[/tex]
Now distribute, multiply every term inside the parenthesis by the term outside of it
[tex](9x^2)(2x-3y)\\\\(9x^2)(2x) + (9x^2)(-3y)\\[/tex]
Simplify,
[tex]18x^3-27x^2y[/tex]
Therefore the solution is (d.) [tex]18x^3-27x^2y[/tex]

Write y=(2)/(3)x+7 in standard form using integers.
A. –2x + 3y = 7
B. 3x – 2y = 21
C. –2x + 3y = 21
D. –2x – 3y = 21
Answer:
Step-by-step explanation:
Write in standard form.
2 x − 3 y = − 21
Write in standard form.
3 x + y = 23
answered: faith1993
Standard form means, move the variables to the left-hand-side and leave the constant all by herself on the right-hand-side, usually sorting the variables, so"x" goes first.
now, there's a denominator, we can do away with it, by simply multiplying both sides by the denominator, so let's do so,
answered: evelynalper08
The standard form of an equation of a line is written as:
Ax + By = C
where A, B and C are constants.
y = –2/3x + 7
2/3x + y = 7
(2/3x + y = 7)3
2x + 3y = 21
The standard form of an equation of a line is written as:
Ax + By = C
where A, B and C are constants.
y = –2/3x + 7 2/3x + y = 7(2/3x + y = 7)32x + 3y = 21
Y= -2/3*x+7 | *3
3y= - 2x+21 | +2x
3y+2x=21 this is the correct answer
You multiply everything by 3 which equals 3y=2x+21 then you switch 21 and 3y which equals -21=2x-3y. Hope this helps
1 Answer. The equation in standard form is 23x−y=7 .
Step-by-step explanation:
answered: Guest
it's equivalent, so we can say that its equal.
let's call the denominator x and the numerador is 18 less then denominator, x - 18.
\frac{2}{5}=\frac{x-18}{x}
multiply
2.x = 5.(x - 18)
2x = 5x - 90
90 = 5x - 2x
90 = 3x
x = 90/3
x = 30

How many different triangles can you make if you are
given these three lengths for sides?
17 cm
13cm
23cm
Answer:
1 triangle can be formed
We are given three side lengths, which are 17cm, 23cm, and 13cm. So, we can form the triangle when;
17 + 23 > 13
17 + 13 > 23
23 + 13 > 17
Since the above conditions are met, then we can form one triangle.
Now, each next triangle with the same sides lengths will be congruent to the first triangle by SSS postulate.
SSS postulate states that: If the three sides of a triangle are congruent to the three sides of another triangle, then the two triangles are congruent.
Thus, only 1 triangle can be formed.

Multiple Select: Multiply and match each of the following
expressions.
A. (x − p) (x + p)
B. (x – 5) (x + 7)
C.(x + p) (x + p)
A.isz? - 2px – pº A.isx? – p2 B.isz? + 2x – 35
B.isx? - 20 – 35 Cisx2 + 2px +p?
Answer:
A. (x − p) (x + p) = x² - p²
B. (x – 5) (x + 7) = x² + 2x - 35
C. (x + p) (x + p) = x² + 2px + p²
Step-by-step explanation:
To find - Multiply and match each of the following expressions.
A. (x − p) (x + p)
B. (x – 5) (x + 7)
C.(x + p) (x + p)
Proof -
A.)
The expression is - (x − p) (x + p)
Now,
(x − p) (x + p) = x(x + p) - p(x + p)
= x(x) + x(p) - p(x) - p(p)
= x² + xp - px - p²
= x² - p²
⇒(x − p) (x + p) = x² - p²
B.)
The expression is - (x – 5) (x + 7)
Now,
(x − 5) (x + 7) = x(x + 7) - 5(x + 7)
= x(x) + x(7) - 5(x) - 5(7)
= x² + 7x - 5x - 35
= x² + 2x - 35
⇒(x − 5) (x + 7) = x² + 2x - 35
C.)
The expression is - (x + p) (x + p)
Now,
(x + p) (x + p) = x(x + p) + p(x + p)
= x(x) + x(p) + p(x) + p(p)
= x² + xp + px + p²
= x² + 2px + p²
⇒(x + p) (x + p) = x² + 2px + p²

The perimeter of a rectangular wooden deck is 90 feet. The deck's length is 5 feet less than 4 times its width. Write a system of equations to represent this situation.
Answer:
width = w
length = 4w - 5
perimeter = 90 feet
substitute these values into the formula for perimeter of a rectangle
90ft = 2( w + 4w - 5)
90ft = 2( 5w - 5)
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)

solve (200 + 200) √100
Answer:
4000
Step-by-step explanation:
200 + 200 {100
400 × 10
4000
Answer:
4000
Step-by-step explanation:
because the 200+200 are in parenthesis that shows that you will need to do it first.
so.. 200+200=400
and now the second part is asking for the square root of 100. We know that 10 times 10 is 100. This means that 10 is the square root of 100.
And for our last step they ask to multiply our two answers.
so 400 x 10= 4000
