2 would be the answer. Replace the x with the three and multiply that with the 2 and then subtract 4.

Step-by-step explanation:

Step 1: Define

Identify

f(x) = 35x + 25

g(x) = 22x + 18

f(4) is x = 4 for function f(x)

g(10) is x = 10 for function g(x)

Step 2: Find Function Values

f(4)

Substitute in x [Function f(x)]: f(4) = 35(4) + 25
Multiply: f(4) = 140 + 25
Add: 165

g(10)

Substitute in x [Function g(x)]: g(10) = 22(10) + 18
Multiply: g(10) = 220 + 18
Add: g(10) = 238

Step 3: Evaluate

Substitute in function values: 5(165) + 2(238)
Multiply: 825 + 476
Add: 1301

The pillars in front of Mr. Jefferson's home are shaped like cylinders with a height of 24 ft and a radius of 8 in. What is the

kkurt [141]

Answer:

The lateral area is $4,608\pi\ in^{2}$ or $32\pi\ ft^{2}$

Step-by-step explanation:

we know that

The lateral area of a cylinder (pillar) is equal to

$LA=2\pi rh$

Remember that

1 ft=12 in

Find the lateral area in square inches

we have

$r=8\ in$

$h=24\ ft$ ----> convert to inches

$h=24*12=288\ in$

substitute the values

$LA=2\pi (8)(288)$

$LA=4,608\pi\ in^{2}$

Find the lateral area in square feet

we have

$h=24\ ft$

$r=8\ in$ -----> convert to feet

$r=8/12=(2/3)\ ft$

substitute the values

$LA=2\pi (2/3)(24)$

$LA=32\pi\ ft^{2}$
