To find the difference of the given expression, first step is to get rid of parenthesis. So, distribute negative sign to each terms of the second parenthesis. Hence,
(9x² + 10x + 4) - (9x² + 5x - 1)
= 9x² + 10x + 4 - 9x² - 5x + 1.
= (9x² - 9x²) +(10x - 5x) + (4 + 1) Group the like terms.
= 0 + 5x + 5 Combine the like terms.
= 5x + 5.
So, first choice is correct.
Hope this helps you!
5+1.5=6.5 yards
90-28=62 degrees
Imagine a right triangle where the
a=6.5
B=?
C=?
We use SOH-CAH-TOA
Tan(62degrees)=(x/6.5)
=12.2 yards
Answer:
X= 20
Step-by-step explanation:
4x + 8 = 88
4x +8 - 8 = 88 - 8
4x = 80
4x/4 = 80/4
X = 20

Ive attached what the graphs will look like, I cannot add the last graph since its the image limit for this website.
Hope this helps, feel free to PM me if you are still having trouble and need the last graph :)
