After distribution the equation 3 (x+5)= 18 will read:
a. 3x + 5= 18
b. 3x + 15= 18
c. 3x + 15= 33
d. 3x - 5 = 18

step-by-step explanation:

i think you should think about the question and not look online.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
