EXTRA POINTS :) what is the value of x??

vlada-n [284]

Answer:

x = 17

Step-by-step explanation:

corresponding interior angles are supplementary, meaning they have to add up to 180 degrees so

6x + 8 + 4x + 2 = 180° then combine like terms ( 6x and 4x, 8 and 2 )

10x + 10 = 180 subtract 10 from both sides

-10 -10

10x = 170 divide each side by 10

/10 /10

x = 17

How do I solve for x?<br> -3x+7=1

inna [77]

Answer:

x=2

Step-by-step explanation:

-3x+7=1

subtract 7 from both sides: -3x+7-7=1-7

simplify: -3x=-6

divide both sides by -3: $\frac{-3x}{-3}=\frac{-6}{-3}$

simplify: x=2

I NEED HELP PLSSS , what is the volume and surface area

GaryK [48]

Given:

The dimensions of the given cuboid are 8 in, 6 in and 7 in.

To find:

The volume and the surface area of the given cuboid.

Solution:

The volume of cuboid is:

$V=l\times b\times h$

Where, l is length, b is breadth and h is height.

$V=8\times 6\times 7$

$V=336$

Therefore, the volume of the cuboid is 336 cubic inches.

The surface area of the cuboid is:

$A=2(lb+bh+hl)$

Where, l is length, b is breadth and h is height.

$A=2(8\times 6+6\times 7+7\times 8)$

$A=2(48+42+56)$

$A=2(146)$

$A=292$

Therefore, the surface area of the cuboid is 292 square inches.
