Answer:
4 because -2x4 is -8 then -5x4 is -20, then you do -8 minus -20 and you get 16, there ya go! :D
Step-by-step explanation:
36, 8 times 4 is 32. After figuring that 4 is the multiple, you would multiply 9 by 4 giving you the N.
Answer:
9x + 7
Step-by-step explanation:
Given
6x + 5y + 3x + 7 - 5y ← collect like terms
= (6x + 3x ) + (5y - 5y ) + 7
= 9x + 0 + 7
= 9x + 7
Each Tube costs $2.65
50.35 divided by 19= 2.65
First way
arcsin(1/4) means that 1/4 sin of the angle.
sin(α)=1/4
sin²α+cos²α=1
(1/4)²+cos²α=1
cos²α=1-1/16 =15/16
cosα=+/-(√15)/4
<span>Second way
</span>
sin(α)=1/4 =opposite leg/hipotenuse
cos(α)=adjacent leg/hypothenuse
adjacent leg =√(hypotenuse²- Opposite²)=√(16-1)=√15
cosα=+/-√15/4
For one value of sinα, possible 2 values of cosα.
