Answer:
8(x+5)
Step-by-step explanation:
8x65 65 miles per hour for 8 hours. Rewrite expression using distributive prop
The answer is 92.
8^2= 64
14/2 = 7
35-7= 28
28+64= 92
Answer:
1.9a
Step-by-step explanation:
6.7a - 4.8a = 1.9a
A=124
B=0.7x+75
124<0.7x+75
49<0.7x
70<x
When you drive more than 70 miles, company A is cheaper
X³ - 2x² - 5x = 0
First, take common factor:
x(x^2 - 2x - 5 )= 0
Now use the quadratic formula to find the roots of the trinomial
x = [- b +/- √(b^2 - 4(a)(c)] / 2a
x = [2 +/-2√6 ]/2
x = 1 + √6 and x = 1 -√6
Then the solutions are:
x =0; x = 1 + √6; x = 1 - √6
That is the las option shown.
