its C
Step-by-step explanation:
thank me later
( 6 + x)(9 + x) =88
54 + 15x + x^2 = 88
x^2 + 15x - 34 = 0
(x + 17)(x - 2) = 0
using zero product property:-
x + 17 = 0 or x - 2 = 0 giving:-
x = -17 , x = 2
x is the amount that the length and width are increased by.
x = -17 is negative and doesn't make sense in this context and can be ignored; so the amount of increase is 2 feet.
Answer: 112%
Step-by-step explanation:
Let x = the cost of the shoes
If the cost of the sweater is 12% more than the cost of the shoes, then 1.12x is the cost of the sweater.
To convert the 1.12x into a percentage, multiply 1.12 by 100
This gives you: 112%
