There are no zeroes for an expression, only for equations.
Assuming equation to be
<span>−7x^2 − 91x − 280=0
-7(x^2+13x+40)=0
-7(x+8)(x+5)=0
by the zero product properties,
x+8=0 => x=-8
or
x+5=0 => x=-5</span>
Answer:
$38
Step-by-step explanation:
If there are three adults (or not-students) then that amounts to $30
(10*3)
Since they all go in one car they only pay $8
Add them all together!
Answer:
B, y = 4x + 1
Step-by-step explanation:
to get it into y- intercept form we need to write it in the form y = mx + b
-8x = 2 - 2y, move 2y to the other side and -8x to the other side they both become positive.
2y = 8x + 2, dividing each by 2
yields y = 4x + 1
Hope this helps
Circumference =
When you plug that in you should have
Solve that and you have your answer(: I would recommend rounding to the nearest hundreth
