Answer:
17
Step-by-step explanation:
6 x 2 = 12 so 12 + 5 = 17
Dylan would have to pay $17.
The first thing to do would be to simplify the equation first. Let's apply the trigonometric functions properties where 1 + tan²x = sec² x. So, we can substitute this to the equation so that it would purely be a function of tangents.
<span>2sec</span>²<span>x-tan</span>⁴<span>x=-1
2(1+tan</span>²x) - tan⁴x = 1
2 + 2 tan²x - tan⁴x + 1 = 0
tan⁴x - 2tan²x + 1 = 0
(tanx -1)² = 0
tanx - 1 = 0
tanx = 1
x = tan⁻¹ 1
x = 45°
So, the solution for the given trigonometric equation is 45° or π/4 radians.

38.25
Step-by-step explanation:
It is 4.5 times 8.5 which is 38.25
Answer:
42p + 21r
Step-by-step explanation:
First look at the parentheses. Since 4p and 2p are the same variables, you can add them.
7(6p + 3r)
now you use the distributive property.
7 x 6p + 7 x 3r
42p + 21r
and then you get you’re answer.
Step-by-step explanation:
A=8B
A+B=180
8B+B=180°
9B=180°
B=20°
so
angle A =8×20=160°
angle B= 20°
