Answer:
36 ft
Step-by-step explanation:
A = lw
Data:
A = 864 ft²
l = length of basement
w = ⅔l
Calculations:
864 = l × ⅔l
864 = ⅔l²
Multiply each side by 3: 2592 = 2l²
Divide each side by 2: 1296 = l²
Take the square root of each side: l = 36
The length of the basement is 36 ft.
Check:
w = ⅔l = 24 ft
864 = 36 × 24
864 = 864
Note: When dealing with the coordination change when the figure is in the state of reflection through x-axis, <em>only switch the signs of the y values</em>.
T(-1,-10) → T'(-1,10)
U(-1,-1) → U'(-1,1)
V(8,-2) → V'(8,2)
W(8,-10) → W'(8,10)
Answer:
slope = 5
y intercept = -3
Equation = y=5x-3
Step-by-step explanation:
-8-7/(-1-2)=5
plug in a point to find y intercept
7=5(2)+b
solve for b
b=-3
write final equation:
y=5x-3

Answer:
there was alot of math here but i got 10
Step-by-step explanation:
so first u add 10 and 2 u get 12 then u multiply 4 then u get 48 and divide that by 4 and then subtract 2 and get 10. hope this helped
