10.) DC
community property
11.) 13+x
community property
12.) 8x-12
distributive property
13.) (2+a)+b
14.) 4(2x+1)= 4+8x
For question 14 you can do 4×2=8x. Then do 4×1=4. It is equal. Just do distributive property for number 14 for 4(2x+1)
Answer: D
Step-by-step explanation:
(5z + 15) - (11z + 2)
= (5z-11z) +(15-2)
= -6z+13
WXY = XYW ( = 41 ) ⇒ XYW is a isosceles triangle
⇒ XW = YW
⇒ 54 = 6x + 6
⇒ 6( x + 1 ) = 54
⇒ x + 1 = 9
⇒ x = 8
ok done. Thank to me :>
Answer:
4cos4x
Step-by-step explanation:
let's use cos
amplitude=4
period=pi/2
2pi/x=pi/2
x=4
no phase shift
y=4cos4x
