Answer:
= x − 4
Step-by-step explanation:
Let's simplify step-by-step.
3x−(2x+4)
Distribute the Negative Sign:
=3x+−1(2x+4)
=3x+−1(2x)+(−1)(4)
=3x+−2x+−4
Combine Like Terms:
=3x+−2x+−4
=(3x+−2x)+(−4)
= x - 4
Answer:
-16(1)^2+60(1)= -16+60=44
Step-by-step explanation:
Answer:
<h3><u>Firs</u><u>t</u><u> </u><u>q</u><u>uestion</u></h3>
To find ? we use sine
sin ∅ = opposite / hypotenuse
From the question
The hypotenuse is 50
The opposite is 25
So we have
sin ? = 25 / 50
sin ? = 1/2
? = sin-¹ 1/2
<h2>? = 30°</h2>
<h3><u>Sec</u><u>ond</u><u> </u><u>q</u><u>uestion</u></h3>
To find ? we use tan
tan ∅ = opposite / adjacent
From the question
the opposite is 8
the adjacent is 33
So we have
tan ? = 8/33
? = tan-¹ 8/33
? = 13.62
<h3>? = 14° to the nearest degree</h3>
Hope this helps you
