4(2x-5)+7(x+2)
bracket means multiplying
do 4(2x+5) first
4*2x=8x
4*-5=-20
7*x=7x
7*2=14
8x-20+7x+14
do the x first
8x+7x=15x
-20+14=-6
answers: 15x-6 or -6+15x
Answer:
% error = 3.3%
Step-by-step explanation:
Percent Error Formula:
% error = ( (MeasuredValue - AcceptedValue) / AcceptedValue ) * 100
% error = ( (12.7 - 12.3) / 12.3 ) * 100
% error = (0.4/12.3) * 100
% error = (0.03252033) * 100
% error = 3.25203252
% error = 3.3%
I am gonna have to go with Latisha's answer.
(x - 3)(x + 4) = x^2 + 4x - 3x - 12 = x^2 + x - 12.......and 4(-3) = -12, -3 + 4 = 1....and the factors are correct
2.375*3.65=8.667
that is the answer
