Find the volume and show work to be brainliest

Answers

Answer:

(7) 1482 in³

(8) 216 yd³

Step-by-step explanation:

Formulas

Volume of prism

= base × height/length

Area of parallelogram

= base × height

Area of trapezium

= (upper base + lower base) × height ÷ 2

(7)

Area of the base = 19×6

= 114 in²

Length = 13 in

Volume = 144×13

= 1482 in³

(8)

Area of the base = (11+7)×12÷2

= 108 yd²

Length = 2 yd

Volume = 108×2

= 216 yd³

Answer:

(7) 1482 in³

can i get help plsssssssssssssssssssssssssssssssssssssss

Answers

Answer:

Let's say X = 4

Then we would rewrite the problem as 2 (4) + 3 = ?

2 × 4 = 8

8 + 3 = 11

------------------------

Do the same here.

2 (4 + 3) = ?

4 + 3 = 7

Rewrite the expression:

2 (7) = 2 × 7

2 × 7 = 14

----------------------

So, no the expressions are not equivalent.

help please, an explanation would be greatly appricatated.

Answers

Answer:

x = -5

Step-by-step explanation:

In both questions you want to get the x alone.

-3x + (-6) = 9

First you want to add 6 to both sides so you'll be left with:

-3x = 15

Next, you want to divide both sides by -3 and you'll get:

x = -5

-4x + (-12) = 8

You want to do the same thing as the first one so you'll add 12 to both sides:

-4x = 20

Then, you will divide both sides by -4 and get:

x = -5
