Hello,
Let's assume i the number of lines,
u(i) the number of regions:
Answer:
Step-by-step explanation:
x² + 9x+8 = (x+1)(x+8)
Answer:
m=-3/7
Step-by-step explanation:
(-4,2), (-3,5)
x1 y1 x2 y2
m=<u>y2-y1</u>
x2-x1
m=<u>5-2</u>
-3-4
m=<u>3</u>
-7
m=-3/7
Well perimeter is lengthx2 and widthx2 so 7x2=14
then 64-14=50
50÷2= 25
length=25
10 and -7 times each other equals -70.
10 plus -7 equals 3.
Hope this helps you! (:
