Pls help me ASAP thank you

6. 8 mi³

7. 72 cm³

Step-by-step explanation:

6. Volume of triangular pyramid = ⅓*A*H

Where,

A = area of triangular base = ½*b*h = ½*3*4 = 6 mi

H = height of pyramid 4 mi

Volume = ⅓*6*4 = 8 mi³

7. Volume of triangular prism = ½*bhl

Where,

b = 3 cm

h = 6 cm

l = 8 cm

Volume = ½*3*6*8 = 72 cm³

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
