Step-by-step explanation:
Add up all the sides together
1+1+7+7 = 16
Correct answer is option C.(-3,-5) and (3,7)
<u>Step-by-step explanation:</u>
Let us take the value of y from equation y=2x+1 and plugin to the equation y=x2+2x-8
so
2x+1=x2+2x-8
taking constants on left hand side and literals on the right hand side
1+8=x2+2x-2x
9=x2
this implies that value of x=+3,-3
now plug in the value of x in the equation y=2x+1
when x=+3
y=2*3+1 = 7
so (3,7)
when x=-3
y=2*(-3)+1 = -5
so (3,-5)
hence the answer is (-3,-5) and (3,7)
