Answer:

x= 5 , 7x = 35

Step-by-step explanation:

Well, first we need to find the value of x.

3x - 9 = -2x + 16

3x + 2x = 16 + 9

5x = 25

x = 5

So, we just need to multiple it by 7

x = 5

7x = 7*5

7x = 35

iVinArrow [24]

Answer:

12 cans

Step-by-step explanation:

The area of the outside of the tank:

radio = half diameter = 4.5 ft.

base: $A_{b} =\pi r^{2} =\pi (4.5)^{2} =20.25\pi$

Top: = base $=20.25\pi$

cylinder: $2\pi rh=2\pi (4.5)(16)=144\pi$

Total area to paint: $144\pi +2(20.25\pi) =184.5\pi =579.6sq.ft.$

Number of cans of paint:

$c=\frac{579.6}{50} =11.59=12$

Answer:

f(-2) = 0

f(1) = 12

f(2) = 5

Step-by-step explanation:

f(-2) will lie in the function $f(x) =x^2 - 4$

$\therefore f( - 2) = {( - 2)}^{2} - 4 = 4 - 4 = 0$

f(1) will lie in the function $f(x) =2x^2 +10$

$\therefore f(1) = 2 {(1)}^{2} + 10 = 2 + 10 = 12$

f(2) will lie in the function $f(x) =5$

$\therefore f(2) = 5$
