I think the answer is c beacause you have to multiply to get the answer
Answer:
d) none of these lines fit the data
Answer:
hope this helps
Step-by-step explanation:
3+x=x²+3x
Simply the equations.
= x+3=x²+3x
Subtract x²+3x from both sides.
x+3−(x²+3x)=x2+3x−(x²+3x)
−x2−2x+3=0
Factor left side of equation.
(−x+1)(x+3)=0
−x+1=0 or x+3=0
Answer:
x=1 or x=−3

now you must first distribute the 2 in the brackets. multiply 2 by h and (-29)

now combine "like terms" (-58) with (-58) and 2h with (-h)

now that h has no coefficient (no number in front) you can bring the -116 over to the other side to isolate the variable (h). remember when you bring a number over the equal sign the signs change so (-116) becomes 166.

now add the two terms together

the final result is 157
