Anyone know how to do this u dont have to say the answer I just dont get it

1. 7

Step-by-step explanation:

The first 4 problems require you to know how to use the square root. Essentially, you want to find the number that times itself will equal the number in your square root. So, for the first problem, for some number x,  x*x=49. Thus, x=7 and that is your answer. I will continue the first 4...just typing

given hc ∥ gd.¯¯¯¯¯¯which statement is true

step-by-step explanation:

∠cbe and ∠deb are same-side interior angles

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
