Step-by-step explanation:
Since AC=BE & DE=DC
then measure angle <CAD=<EBD =X
Then< DAB =90-x
And <ABD= 90-X
then measure angle 1= measure angle 2
It is 1.55 times the value of the second number.
Answer:
2 tacos = $6
1 tacos = $3
6 tacos = 6 X 3
= $18
18$ is the cost for 6 tacos
The answer would be B because I did this equation on a sheet of paper and I did the parentheses first which led me to my final answer B.
Answer:The roots are:

and
Explanation:First, we will need to expand the bracket on the left and then put teh equation i standard form which is:
ax² + bx + c = 0
This can be done as follows:
(x+5)² = 10
(x)² + 2(x)(5) + (5)² = 10
x² + 10x + 25 - 10 = 0
x² + 10x + 15 = 0
By comparison, we can find that:
a = 1
b = 10
c = 15
Now to get the roots, we would need to use the quadratic formula shown in the attached image.
By substitution, we would find that:
either x =

or x =

Hope this helps :)
