Answer:
C
Step-by-step explanation:
No problem!
The final 4 is in the numerator, not the denominator.
5² × 4 × 5 × 4² / 5 (4)
= 25 × 4 × 5 × 16 / 5 × 4 . . . . . exponents are computed first
= 100 × 5 × 16 / 5 × 4 . . . . . . . multiplication and division left to right in order
= 500 × 16 / 5 × 4
= 8000 / 5 × 4
= 1600 × 4
= 6400
12:15 = 8:X
X=cardboard box shadow
you find x by treating this equation like a proportion.
so 15(8)÷12=x
X=10
Answer:
Surface Area would be 200² inches.
Step-by-step explanation:
SA=2(12*9)+2(9*2)+2(12*2)
SA=2(108)+2(18)+2(24)
SA=216+36+48
SA=200² in.
