The way it's written it's
Simplify the following:
7 X^3 + 4 X^2 + 2 X^2 + 3 X + X + 2 + 5
Grouping like terms, 7 X^3 + 4 X^2 + 2 X^2 + 3 X + X + 2 + 5 = 7 X^3 + (4 X^2 + 2 X^2) + (3 X + X) + (2 + 5):7 X^3 + (4 X^2 + 2 X^2) + (3 X + X) + (2 + 5)
4 X^2 + 2 X^2 = 6 X^2:
7 X^3 + 6 X^2 + (3 X + X) + (2 + 5)
3 X + X = 4 X:
7 X^3 + 6 X^2 + 4 X + (2 + 5)
2 + 5 = 7:Answer: 7 X^3 + 6 X^2 + 4 X + 7

Find the volume of each figure

konstantin123 [22]

Answer:

1) 17.5×14×64

→ 1568 in³

2) volume= 0.5×3.6×10×5=

→ 90

3) d= 13, r=13/2= 6.5, h= 19

→ v= πr²h

→ π(6.5)²×19

→ 2521.91 mm³

4) Base Area= a+b/2×h

→ (37+15)/2×25.7 cm²

→26×25.7 cm²

→ 668.2 cm²

height= 20cm

voulme = 668.2×20

→ 13364 cm²

5) L×W×H

→ 25×7×18

→ 175×18

→ 3150 ft³

6) v=πr²h

→ π(3.2²)(8)

→ 81.92π

→ 257.36 km²
