Answer:
5^2 x 2^0 = 25 or 5^2 = 25
Step-by-step explanation:
5^2 = 25
2^0 = 1 (Anything raised to the zero power equals one no matter what the number is)
25 x 1 = 25

Answer:
For the rectangle
Length=ℓ
Breadth=b
Area is 12 cm2
ℓb=12
Perimeter is 16 cm
2(ℓ+b)=16
ℓ+b=8
Substitute b=12ℓ from first equation
ℓ+12ℓ=8
ℓ2+12=8ℓ
ℓ2−8ℓ+12=0
Use quadratic formula (x=−b±√b2−4ac2a) to find ℓ
ℓ=−(−8)±√(−8)2−(4×1×12)2×1
ℓ=8±√162
ℓ=8±42
ℓ1=8+42=6
ℓ2=8−42

Answer:
-17
Step-by-step explanation:
Solving for y, we find ...
-11y -4 = 7
-11y = 11 . . . . . . . add 4
y = -1 . . . . . . . . . divide by -11
Then the expression of interest has the value ...
9y -8 = 9(-1) -8 = -9 -8
9y -8 = -17
