Answer: factorise the equation 49x^2+70x+25
Step-by-step explanation:
49x^2+70x+25
(7x)^2+2*7x*5+(5)^2
(7x+5)(7x+5)
therefore the sides of the square are (7x+5)(7x+5)
Answer:
1- 12 inches
2- 12 x .7=8.4 inches next biggest doll
3- 8.4 x .7=5.88 inches next biggest doll
4-5.88 x .7=4.12 inches the last doll.
Step-by-step explanation:
Answer:
the measure of AB equals the measure of BC
2x+1=3x-4
4+1=3x-2x
5=x
BC=3x-4=3*5-4=15-4=11
AB=2x+1=2*5+1=10+1=11
AC=AB+BC=11+11=22
Step-by-step explanation:
I believe the answer is A because a reflection over the y-axis and one over the x-axis is the same as a reflection over the origin<span />
