Solve for x. 4(2-x)+13=2x+3

Mathematics
1 answer:
gregori [183]3 years ago
4 0

Answer:

x = 3

Step-by-step explanation:

4(2-x)+13=2x+3

distribute the 4.

8 - 4x + 13 = 2x + 3

combine like terms.

21 - 4x = 2x + 3

18 = 6x

divide by 6.

x = 3

check.

4(2 - 3) + 13 = 2(3) + 3

4(-1) + 13 = 6 + 3

-4 + 13 = 9

9 = 9

correct!

Joseph made a model rocket by attaching a cone
Lerok [7]

Answer:

Area = 270π inches squared. Volume = 550π inches cubed

Step-by-step explanation:

Surface Area:

Cylinder Area=2πrh+2πr^2= 180π+50π=230π inches squared.

Cone Area = πr(r+√(h^2+r^2)) = 5π(18) = 90π inches squared.

Total Area = 230π+90π = 320π inches squared.

Total Area - base = 320π-50π = 270π inches squared.

Volume:

Cylinder volume = πr^2h = 450π inches cubed

Cone volume = πr^2(h/3) = 100π inches cubed

Total Volume = 550π inches cubed

The length of a rectangular window is 5 feet more than its width, w. The area of the
Ilya [14]

Answer:

The equation could be used to find the dimensions of the  window would be:  w^{2}  + 5w = 36

Step-by-step explanation:

as

  • The length of a rectangular window is 5 feet more than its width, w.

and

  • The area of the  window is 36 square feet.

So it means

l = w + 5

A = lw

36 = (w + 5)w

w^{2}  + 5w = 36

Therefore, the equation could be used to find the dimensions of the  window would be:  w^{2}  + 5w = 36
