Im not sure why you said ur wrong b/c i got the same answer
f(x) = -15+ 7
f(x) = -8
She will need 13 one-fourth cups.
(4 one-fourths times 3 = 12 cups plus another one-fourth)
Hope this helps you!!!
Lets x = width
height = 2x - 4
A = 1/2 b h
63 = 1/2 (x)(2x-4)
126 = 2x^2 - 4x
2(x^2 - 2x - 63) = 0
2(x - 9)(x + 7) = 0
x - 9 = 0; x = 9
x + 7 = 0; x = -7
so width = 9
height = 2(9) - 4 = 18 - 4 = 14
answer
width = 9 in
height = 14 in
Answer:
Step-by-step explanation:
The product of 3 and 9 just means to multiply 3 and 9. This is written as:
3 x 9
14 more than this just means to add 14 to the above.
3 x 9 + 14
