The perimeter of an equilateral triangle is 18p - 24. Write an expression to represent the length of each side.

grandymaker [24]

Answer:

6p -8

Step-by-step explanation:

The three sides of an equilateral triangle are all the same length. (This is the literal meaning of "equilateral.") So, the length of one side is 1/3 the total length.

each side = $\dfrac{18p-24}{3}=\dfrac{18p}{3}-\dfrac{24}{3}=6p-8$

Determine the measure of ∠Q, rounded to the nearest tenth of a degree. images attached.

const2013 [10]

Answer:

Step-by-step explanation:

Using the Sine rule in Δ QRS , that is

$\frac{q}{sinQ}$ = $\frac{r}{sinR}$ , that is

$\frac{15}{sinQ}$ = $\frac{12}{sin50.1}$ ( cross- multiply )

12× sinQ = 15 × sin50.1° ( divide both sides by 12 )

sinQ = $\frac{15sin50.1}{12}$ , thus

Q = $sin^{-1}$ ( $\frac{15sin50.1}{12}$ ) ≈ 73.5° ( to the nearest tenth )

Find (g*f)(3) f(x)= 7x + 8 g(x)= -1/x

Sophie [7]

Answer:

-21-24/x

Step-by-step explanation:

f(x) is a function on his own which is f(x)=7x+8

we multiple it with another function which is g(x)=-1/x

that gives us (g*f)=-7-8/x

then multiple it by 3 we have -21-24x
