Since there are no numbers, i will assume that the length of recess is 1 minute, or x. if social studies is 4 more than 2 times the length of recess, we can use the equation x*2+4 to solve the problem. the end result will be 6 minutes. Social studies is 6 minutes longer than recess
Answer:
Step-by-step explanation:
r²+8r=−7
Step 1: Subtract -7 from both sides.
r²+8r−(−7)=−7−(−7)
r²+8r+7=0
Step 2: Use quadratic formula with a=1, b=8, c=7.
r=
Answer:
-2

i got it right
Answer:
If you are trying to solve by substitution then you have 2 different possibilities of answer forms.
First Possibility: (Point form) (16,8)
Second Possibility: (equation form) x=16, y=8
