In-s [12.5K]

Answer: 1590cm^3

Step-by-step explanation:

V=\frac{3\sqrt{3} }{2}a^2h

a = base

h = height

V=\frac{3\sqrt{3} }{2}(6cm)^2(17cm)

Solve the parentheses squared first.

V=\frac{3\sqrt{3} }{2}(36cm^2)(17cm)

2 and 36 can be simplied

2/2=1

36/2=18

V=3\sqrt{3}(18cm^2)(17cm)

V=3\sqrt{3}(306cm^3)\\ V=1590.02cm^3

Rounded to the nearest whole number... 1590cm^3

Answer:

-2

Step-by-step explanation:

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

−(3v+1)+7(6v+6)=−37

Step 1: Simplify both sides of the equation.

−(3v+1)+7(6v+6)=−37

−3v+−1+(7)(6v)+(7)(6)=−37(Distribute)

−3v+−1+42v+42=−37

(−3v+42v)+(−1+42)=−37(Combine Like Terms)

39v+41=−37

39v+41=−37

Step 2: Subtract 41 from both sides.

39v+41−41=−37−41

39v=−78

Step 3: Divide both sides by 39.

39v

39

=

−78

39

v=−2

Answer:

v=−2
