need help with surface area​

Answer:

a.3p

b 5s

c 2r -76 this can be the answer

Answer: A) 3p , B) 5s , C) -6r+8t-76

Step-by-step explanation:

A ) 4p + 2p – 3p

combine like terms :-

(4p+2p+-3p)

(4p+2p+-3p) = 3p

= 3p

B ) 9s- 5s + 2s-S

combine like terms :-

( 9s-5s+2s+-s)

( 9s-5s+2s+-s) = 5s

C )  8t + 3r - 76 - 9r​

combine like terms :-

(3r+-9r)+(8t)+(-76)

= - 6r+8t+-76

Step-by-step explanation:

S A S congruence rule: Two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of other triangle.

If two triangles are congruent by SAS, and the angle is 90, then by CPCT{corresponding part of congruent triangle)  the hypotenuse of the two triangles will be congruent.

Now, as hypotenuse  and  one leg are congruent in both triangles, we can apply RHS congruent

HOPE THIS HELPS

Step-by-step explanation:

The area = length * Width.

We know the width = X+6 inches and Area = x^3+3x^2–18x.

This problem can be solved just by dividing the area by width and we get a quotient as X^2–3x.

So the length is x^2–3x inches.

The length of the rectangle is [tex]\rm x(x-3)[/tex].

Given

The area of the rectangle = [tex]\rm x^3+3x^2-18x[/tex] square inches

The width of the rectangle = x + 6 inches

The area of the rectangle is equal to the product of length and width of the rectangle.

Let the length of the rectangle be L.

The area of the rectangle is given by;

[tex]\rm Area \ of \ the \ rectangle =Length \times Width\\\\[/tex]

Substitute all the values in the formula;

[tex]\rm Area \ of \ the \ rectangle =Length \times Width\\\\\rm x^3+3x^2-18x= L \times (x+6)\\\\L=\dfrac{ x^3+3x^2-18x}{x+6}\\\\L = \dfrac{ x(x+6)(x-3)}{x+6}\\\\ L = x (x-3)[/tex]

Hence, the length of the rectangle is [tex]\rm x(x-3)[/tex].

1/2 = 8/16

3/4 = 12/16

8 + 11 + 8 + 12 = 39

Therefore, Joey walked 39/16 or 2 7/16 miles in total

Answer:

Step-by-step explanation:

Solving

5x + -2y = 12

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2y' to each side of the equation.

5x + -2y + 2y = 12 + 2y

Combine like terms: -2y + 2y = 0

5x + 0 = 12 + 2y

5x = 12 + 2y

Divide each side by '5'.

x = 2.4 + 0.4y

Simplifying

x = 2.4 + 0.4y

Step-by-step explanation:

use the formula m = y2- y1 / x2 - x1

Answer:

Step-by-step explanation:

The slope of a line can be found using any two points of a line and the slope, m, is defined as

m=(y2-y1)/(x2-x1), we have points (-1,-3) and (0,6) so

m=(6-(-3))/(0-(-1))

m=9/1

m=9
