First I would find the base, which is a square so 10x10=100
then find the triangle (a=1/2bh) a=1/2(12)(10) a=1/2(120) a=60
since there are four triangle sides do 60x4 which equals 240, so then add the sides to the base 100+240=340, the answer is A
Slope formula = y2 - y1/ x2 - x1
SF = 3 - (-3)/ 2 - 5
SF = 6/ -3
Slope = -2
Now we need to find b (the y-intercept)
y = mx + b
y = -2x + b
3 = -2(2) + b
3 = -4 + b
+4 +4
7 = b
The equation of the line should be:
y = -2x + 7
Answer:
-9
Step-by-step explanation:
The answer is -9 because you always take away a nine for ex 47-9 is 38
