(x+5)(x+5)=49
solve the equation for x

X=2

Step-by-step explanation:

We can change the left side of the equation to (x+5)² which gives us

(x+5)²=49  now to get rid of the squared we can take the square root of both sides which gets us to x+5=7 and now subtract 5 from both sides to get your final answer of x=2

I hope this helps and please don't hesitate to ask if there is anything still unclear!

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
