Answer:

Step-by-step explanation:

3x + 12 and 105 are alternate exterior angles because A || B and B || C.

If the two or more lines are parallel, then the alternate exterior angles are equal.

3x + 12 = 105

Substract 12 on both sides,

3x = 105 - 12

3x = 93

Divide 3 on both sides,

x = 93 / 3

x = 31

Solve f(-4) for f(x) = 7x - 4x

Strike441 [17]

Answer:

-12

Step-by-step explanation:

What you have to do is plug -4 into the function as a puzzle. So, replace all x with -4.

f(-4) = 7(-4) - 4(-4) = -28 + 16 = -12

Step-by-step explanation:

$\begin{array}{ccc}1&-&d\\2&-&c\\3&-&a\\4&-&b\\5&-&f\\6&-&e\end{array}$

Value 1:

r = 5ft, h = 10ft. Substitute:

$SA=2\pi(5)(10)+2\pi(5^2)=100\pi+50\pi=150\pi\ ft^2$

Value 2:

r = 2in, h = 4in. Substitute:

$V=\dfrac{1}{3}\pi(2^2)(4)=\dfrac{1}{3}\pi(4)(4)=\dfrac{16\pi}{3}\\\\\pi\approzx3.14\to V\approx\dfrac{(16)(3.14)}{3}\approx16.75\ in^3$

Value 3:

r = 6m. Substitute:

$V=\dfrac{4}{3}\pi(6^3)=\dfrac{4}{3}\pi(216)=4\pi(72)=288\pi\ m^3\\\\\pi\approx3.14\to V\approx288(3.14)=904.32\ m^3$
