Multiply 88 by 7, then multiply 88 by 3 and move the decimal point one to the left. Then add those two numbers. That's your answer.
Answer:
LINEAR function constant slope = 2
Step-by-step explanation:
We see points (-3, -11), (-2, -9), (-1, -7), (1, -3) , (2, -1)
slope: m = (-9 - -11)/(-2 - -3) = 2/1
m = (-7 - -9)/(-1 - -2) = 2/1
m = (-3 - - 7)/(1 - -1) = 4/2 = 2
m = (-1 - -3)/(2 - 1) = 2/1 = 2
The width of the border will be about 2.5 feet.
The area of the rug is 9 by 7. Let's call the width of the border x. Therefore, the length of the rug will switch to 9 + 2x. The border is on both sides of it, so we add on 2x. Then, the width is 7 + 2x.
The area of the room is therefore: (9 + 2x)(7+ 2x).
We know the area of the room, so we can write and solve the following equation.
(9 + 2x)(7 + 2x) = 167
4x^2 + 32x + 63 = 167
4x^2 + 32x - 107 = 0
At this point, use the quadratic formula and x will equal about 2.5.
