Answer:
(x - 8)(x + 7)
Zeroes: x = 8, x = -7
Step-by-step explanation:
Find factors of -56 that add to -1.
-8 and 7
The factored form is:
(x - 8)(x + 7)
The zeroes for this polynomial are x = 8 and x = -7
Answer:
x=-11.9
Step-by-step explanation:
Area of the triangle = (1/2)*base*height
base = x
height = altitude = x+6
Area of the triangle = (1/2)*x*(x+6) = 108
(1/2)*x*(x+6) = 108
x²+6x-216 =0
(x+18)(x-12)=0
x=-18, or x=12
We can use only positive value, so x=12.
Base =12 cm.
Answer:
D
Step-by-step explanation:
6% of 40 is 2.4, 40.00+ 2.40=42.40
Only 19 is a function because a function only has one y value for every x value. For the other graphs, there are at least two y values for each x value.
