x^2+2x-99
Answer:
for question #1) 6 times n + 12 = 60
Step-by-step explanation:
it works trust me
ps. im in high school in a GT math class
First you have to figure out the GCF (Greatest Common Factor) of 8 and 10. When you figure that out, the GCF is 2. So then, you would divide 2 by 8 and 10, then you should get the answer which is 4/5.
4x+4y=-9
first change into yintercept form
y=-x-9/4
to find yintercept let x=0
y=-0-9/4
y=-9/4 or -2.25
to find xintercept let y=0
0=-x-9/4
x=-9/4
so the x and y coordinates are -2.25 and -2.25 respectively
