What is the answer to this equation. -g+2(3+g)=-4(g+1)
Stells [14]

Answer:

The answer to the given equation -g+2(3+g)=-4(g+1) is g=-2

Step-by-step explanation:

Given -g+2(3+g)=-4(g+1)

To solve the given equation :

-g+2(3+g)=-4(g+1)

Applying the distributive property we get

-g+2(3)+2(g)=-4(g)+(-4)(1)

-g+6+2g=-4g-4

g+6=-4g-4 ( adding the like terms )

g+6-(-4g-4)=-4g-4-(-4g-4)

Applying the distributive property we get

g+6-(-4g)-(-4)=-4g-4-(-4g)-(-4)

g+6+4g+4=-4g-4+4g+4

5g+10=0 ( adding the like terms )

5g+10-10=0-10

5g=-10 ( adding the like terms )

g=-\frac{10}{5}

g=-2

Therefore g=-2

The answer to the given equation -g+2(3+g)=-4(g+1) is g=-2

The surface area of a rectangular prism is 250 cm 2. If its height is 10 centimeters, and its width is 5 centimeters, what is it
Minchanka [31]

Answer:

V=250\ cm^{3}

Step-by-step explanation:

step 1

Find the length of the base L

we know that

The surface area of a rectangular prism is equal to

SA=2B+PH

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

substitute

SA=2(LW)+2(L+W)H

we have

W=5\ cm

H=10\ cm

SA=250\ cm^{2}

substitute in the formula and solve for L

250=2(5L)+2(L+5)10

250=10L+20L+100

30L=250-100

L=5\ cm

step 2

Find the volume of the rectangular prism

The volume is equal to

V=(LW)H

we have

W=5\ cm

L=5\ cm

H=10\ cm

substitute

V=(5*5)*10=250\ cm^{3}
