Mathematics
1 answer:
crimeas [40]3 years ago
8 0

Answer:

A.

Step-by-step explanation:

A quadratic inequality looks like a quadratic equation, but with signs

<, >, ≤, or ≥

instead of sign =

You are given one equation (the first one, because the sign is =) and two inequalities (the last two beacause the signs are < and > respectively).

Thus, correct option is A,

y=7x^2+5x-7

is not a quadratic inequality (it is a quadratic equation)

They will need 125 square feet

You have to find the area of the total which will be :

Then find the small area that is missing
5 x 7 = 35 square feet

Subtract: 160 - 35 = 125 square feet
