Find The Solution(s) to (x+3)square=49. check all the apply

-10, 4

Step-by-step explanation:

(x+3)^2=49

Take the square root of each side

sqrt((x+3)^2)=±sqrt(49)

x+3 = ±7

Subtract 3 from each side

x+3-3 =  ±7 -3

x = ±7 -3

x = 7-3 =4

 and

x = -7-3 = -10

.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
