If 2x-4(3-x)=18, then x=_____? Can someone please help me with this problem

denis-greek [22]

Answer:

Answer is below

Step-by-step explanation:

Simplify both sides of the equation.

$2x-4(3-x)=18\\2x+(-4)(3)+(-4)(-x)=18$

DIstribute

$2x+-12+4x=18\\(2x+4x)+(-12)=18$

CLT

$6x+-12=18\\6x-12=18$

Add 12 to both sides.

$6x-12+12=18+12\\6x=30$

Divide both sides by 6.

$\frac{6x}{6} =\frac{30}{6}\\ x=5$

Given the points below, find XY. Round to the nearest hundredth. X(-8, 2) and Y(7,-4)

Tasya [4]

Answer: 16.16

Step-by-step explanation:

xy in this situation, will be the distance between the two points.

(-8,2) (7,-4) Find the distance between the points

To ind the distance, find the difference in the x and y values,square them and add them to find the obtained number square root.

2-(-4) = 6

-8 - 7 = -15

6^2 + (-15)^2 = d^2 where d is the distance

36 + 225 = d^2

261 = d^2

d= $\sqrt{261}$

d= 16.1554 rounded to the nearest hundredth is 16.16

What is the area of this face? A.150in2 B.100in2 C.400in2 D.200in2

Levart [38]

Answer:

200 in squared.

Step-by-step explanation:

The top face has a height of 10, it also has a side length of 10. 5 plus 5 equals 10. These faces are squares, so the sides are equal. In this case, they 10 by 10. To find the of the face you do 10 times 10 times 2 because there are 2 figures, or you can find the area of one (100) and the area of the other (100) and add the areas up to get the area of the face. Hope this helps!
