We know that
side AB is parallel to side CD
then
∠A=∠D
∠B=∠C
therefore
(2x+6)/10=(x+6)/8-------------> 8*(2x+6)=10*(x+6)------> 16x+48=10x+60
16x-10x=60-48----------> 6x=12---------> x=2
so
AE=2x+6-------> 2*2+6--------> AE=10
the answer is AE=10 units
Answer:
18ft
Step-by-step explanation:
i can't lay out the formula
Answer:
where is the number line at?
Answer:
(x+2)^2+(y-3)^2=100
Step-by-step explanation:
so the equation is (x-h)^2+(y-k)^2=r^2
(h,k)=center
r^2=radius
in this case (h,k)=(-2,3)
r^2=r^2
10^2=100
(x-(-2))^2+(y-3)^2=100
Hope fully that helps :)
Question 1:
(6x+1)/7 = (18x-2)/14
Multiply both sides by 14
2(6x+1)=18x-2
12x+2=18x-2
Subtract both sides by 12x and add both sides by 2
4=6x
Divide both sides by 6
x = 2/3
Question 2:
Add all the components
2+3+4=9
Divide that from 63
63/9 = 7
Multiply that by 3, Alana's portion.
7*3 = 21
Question 3:
3ab : 27ab
Divide both sides by 3ab
1 : 9
That's one answer.
Multiply both sides by 2
2 : 18
That's another answer.
Multiply both sides of 1:9 by 9a
9a : 81a
That's another answer, and that's all of it.
Hope this helps! :)
