your answer is 44.0 feet
Answer: y = 5x -9
Step-by-step explanation:
first grt slope:
m = rise / run
m = (11- -14) / (4 - -1)
m = (25) / (5) = 5
y - 11 = 5* (x - 4)
Y = 5x -9

The two numbers multiply to 64 and add up to negative 16 are -8, -8.
What is Algebraic expression ?
Algebraic expressions are numbers expressed using letters or alphabets without specifying their values. Algebra taught us how to express unknown values using letters such as x, y, and z. There can also be a single value that is placed before and multiplied by a variable in an algebraic expression in addition to these letters, which are called variables.
Let us assume first number be = x
and, let the second number be = y
then,
multiplication of two number will be :
xy = 64...(1)
addition of two numbers will be -16 that is :
x + y = -16..(2)
we have :
(x+y)² - (x-y)² = 4xy
(x-y)² = (x+y)² - 4xy
(x-y)² = (-16)² - 4 x 64
(x-y)² = 256 - 256
(x-y)² = 0
(x-y) = 0
x = y
Now, from equation (2) we have ":
x + y = -16
x + x = -16
2x = -16
x = y= -8
Therefore, the two numbers multiply to 64 and add up to negative 16 are -8, -8.

If the width of the deck is 3 m less that the length. The length is 8m. then the area to be waterproofed is 40 m²
A rectangle is a quadrilateral with four right angles
The area of Rectangle is length times of width.
Given that Ms. Luna is waterproofing the top of a rectangular wood deck.
The width of the deck is 3 m less that the length.
Width=Length-3
Length=8
Area of rectangle=Length×Width
=Length×(Length-3)
=8×(8-3)
=8×5
=40 m²
Hence, If the width of the deck is 3 m less that the length. The length is 8m. then the area to be waterproofed is 40 m²

Answer:
40 m
Step-by-step explanation:
First we have to find the width. the width is 3 less than the length, which is 8... so the width is 5. Area is found by multiplyign length times width to get 40 m.
