The answer is 76.

2 times 5 is 10. There are two sides so 10 times 2 is 20.

4 times 5 is 20. There are two sides so 20 times 2 is 40.

4 times 2 is 8. There are two sides so 8 times 2 is 16.

20+40+16 is 76.

How do you solve this math problem-2(x+3y)=18

ss7ja [257]

Greetings!

Solve for <em>x</em>.
$-2(x+3y)=18$
Distribute the Parenthesis. <em>How?</em> Multiply all of the terms inside the parenthesis by the number outside the parenthesis.
$(-2)*x+(-2)*3y=18$
$-2x-6y=18$
Add 6y to both sides.
$(-2x-6y)+6y=(18)+6y$
$-2x=18+6y$
Divide both sides by -2.
$(-2x)/-2=(18+6y)/-2$
The Answer Is:
$x=-9-3y$
$x=-3y-9$

Hope this helps.

Answer:

$12x^2+9x$

Step-by-step explanation:

The formula of the area of a triangle is $\frac{bh}{2}$ . Plugging in the given base and height values, you get $\frac{(4x+3)(6x)}{2}=\frac{24x^2+18x}{2}=12x^2+9x$ . Hope this helps!
