Answer:
Step-by-step explanation:
7) 2ab + 4ac = 2*a*b + 2 *2 *a*c
= 2a(b + 2c)
8) ac - a²c² = c( a - a²c)
bc - abc = c(b - ab)
9) b²+ 4b - 5 = b² + 5b - 1b - 5
= b(b + 5) - 1(b + 5)
= (b +5)(b - 1)
b² + 8b + 15 = b² + 5b + 3b + 15
= b(b + 5) + 3(b + 5)
= (b + 5 )(b + 3)
Answer:
(3, -2)
Step-by-step explanation:
after flipping the triangle over the y axis the new point A would be at (1,1)
then following the translation the point would move right twice and down twice leaving the new point A at (3, -2)
Her present age would be 5 because 4m=m+5 which would then turn into 3m=15 because you would subtract the m from both sides and end up with 3m+15, then you would divide 3 to both sides which would then give u an answer of m=5
We can set up a proportion to figure out how many laps out of 200 laps is 57% out of 100%
Cross multiply
The answer is 114 laps.
