Solve for x to the nearest tenth

Using the pythagoras theorem

Let's say the hypotenuse of the first diagram is b

b²=4²+2²

b²=16+4

b²=20

b=✔(20)

In finding x , b will be the opposite and the x be the hypotenuse

x²=(✔20)²+7²

x²=20 +49

x²=69

x=8.31

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
