Answer:
A 11x16
Step-by-step explanation:
Let the length of rectangle be l and width be w.
Then given that perimeter = 2l+2w = 54
l+w =27
w=27-l
Also area = lw = 176
Substitute for w to get
l(27-l) = 176
-l^2+27l-176=0
(l-16)(l-11)=0
Length = 16 cm
or 11 cm
If length =16 width =11 or if length = 11, width =17
Hence answer is
11x16 i.e. option A
25%
difference between 8 and 10 is 2, so 8 would need to increase by 2 to get to 10.
2 is 1/4 of 8, and 1/4 is 25%
answer is 25%
-1/5x -4/5 = y
f(x) = -5x -4
y = -5x-4
Switch x and y
x = -5y -4
Solve for y
Add 4
x+4 = -5y
Divide by -5
-1/5x - 4/5 = -5y/-5
I believe its
y plus 4 multiplied by 3
Hope this helps!
