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.

The surface area of the prism is ______ square units. All measurements in the image below are in units. (Input whole number only

Marina CMI [18]

Answer:

Step-by-step explanation:

Surface area of triangular prism = bh + L(s1 + s2 + s3)

Where,

b = 3

h = 4

L = 3.5

s1 = 3

s2 = 4

s3 = 5

Plug in the values into the equation

Area of the triangular prism = 3*4 + 3.5(3 + 4 + 5)

= 12 + 42

= 54 units²
