(fg)(x) = [f(x)][g(x)]
(fg)(x) = (4x - 5)(3) = 12x - 15

How Do I Find The Answer To 320 = 3x + 16

ruslelena [56]

｡☆✼★ ━━━━━━━━━━━━━━ ☾

320 = 3x + 16

-16 from both sides

304 = 3x

/3 on both sides

x = 304/3

I need help solving the volume of the triangular prism pleaseQuestion 11

Korvikt [17]

Let us begin by defining the formula for finding the volume of a prism.

The volume of a prism can be found using the formula below:

$\text{Volume = base area }\times\text{ height}$

For the given prism, the base is a right-angled triangle. The dimensions of the prism are:

base height = 8 ft

height = 3ft

base length =6 ft

length of the hypothenuse = 10ft

Hence, the volume of the prism is:

$Volume\text{ = Area of the right-angled triangle }\times\text{ height}$

Substituting the given dimensions:

$\begin{gathered} \text{Volume = }\frac{1}{2}\text{ base length }\times base\text{ height }\times\text{ height} \\ =\text{ }\frac{1}{2}\text{ }\times\text{ }6\text{ }\times\text{ 8 }\times\text{ 3} \\ =\text{ }72\text{ } \end{gathered}$

Hence, the volume of the prism is 72 cubic feet

Answer: 72 cubic feet

Which relationship is always true for the angles x, y, and z of triangle MNP?

Reil [10]

In every triangle, all the measures of the angles combined is 180 degrees.

So x + y + z = 180 degrees

If y varies directly as x, and y=14 when x=3.5 find y when x=2

quester [9]

y varies directly as x

y ∞ x

y=14 when x=3.5

y = kx

k is a constant, when multiplied by x, you get y

14 = 3.5k

Solve to find k:

14/3.5 = k

14/3.5 = 4

k = 4

y = 4x

Find y when x=2

y = 4x

y = 4(2)
