Simplify the expression 2x+3(x-2)-3(x-6)

A. 2x + 12
B. 2x - 8
C. 8x - 24
D. 2x - 24

Answers

$2x+3(x-2)-3(x-6) \n \n 2x + 3x - 6 - 3x + 18 \ / \ expand \n \n (2x + 3x - 3x) - 6 + 18 \ / \ gather \ the \ like \ terms \n \n 2x - 6 + 18 \ / \ simplify \n \n 2x + 12 \ / \ simplify \n \n$

The final result is A) 2x + 12.

2x+3(x-2)-3(x-6)You would first distribute.So:2x+3x-6-3x+18Then you would combine like terms, like so:2x+3x-3x= 2x-6+18= 12So it'd be:2x + 12Which is answer choice AHOPE THIS HELPS!!(:

Help with some math homework? The area of a triangle is 110 square inches. the height of the triangle is 8 less than 3 times its base. what are the height and base of the triangle?

Answers

A = h x b; where A = area of a triangle; h = height of the triangle; b = base of the riangle;
So, we have the equation : 110 = (3b - 8)b;
We solve the equation 3b^2 - 8b - 110 = 0;
The positiv solution is b = 7.53 cm;
h = 3 x 7.53 - 8;
h = 14.59 cm;
