Step-by-step explanation:
7p – 3q
if p= 8 and q = -5
7(8)-3(-5)
56+15
=71
Answer:
rong answer is 18
I think the right answer is 0.75
Step-by-step explanation:
Our equation looks like:

This means that we will need to distribute. This means that we need to multiply everything inside the parenthesis by the number outside of the parenthesis. (<em>Note: you only distribute when variables are involved.)</em>

Simplify:

We cannot simplify any further, so we know that our equation, until we know what x equals, is
.
Answer:
A = 41.4°
Step-by-step explanation:
Reference angle = A
Length of Adjacent side = 6
Length of Hypotenuse = 8
Apply the trigonometric function, CAH.
Cos A = Adj/Hyp
Substitute


A = 41.4° (approximated to the nearest tenth)
