Answer:
s for length of either equal side
b for the unequal side
b=-2+2*(s+s) and 2s+b=40
b=2*2s-2
b=4s-2
2s+4s-2=40
6s-2=40
6s=42
s=7
b=4*7-2
b=28-2
b=26
select two points on the line, and plug into this formula y2-y1 over x2-x1
Answer:
The answer is 170
Step-by-step explanation:
Because 8 + 9 = 17, if we multiply all of these values by ten or add a zero to the end of each number, we should get
80 + 90 = 170
