Answer:
3
Step-by-step explanation:
The value of "a" is the coefficient of x^2, so we know that is 2.
__
<u>Solve for h</u>
Now, we have ...
2x^2 -8x +7 = 2(x -h)^2 +k
Expanding the right side gives us ...
= 2(x^2 -2hx +h^2) +k
= 2x^2 -4hx +2h^2 +k
Comparing x-terms, we see ...
-4hx = -8x
h = (-8x)/(-4x) = 2
__
<u>Solve for k</u>
Now, we're left with ...
2h^2 +k = 7 = 2(2^2) +k = 8 +k
Subtracting 8 we find k to be ...
k = 7 -8 = -1
__
And the sum of constants a, h, and k is ...
a +h +k = 2 +2 -1 = 3
The sum of the constants is 3.
Corresponding angles are congruent and appear on the same side of the transversal (the dividing line). Out of the answer choices, letter A (angles 1 and 5) fit that description. Hope this helped
For the first one, it’s 1.2*10^9
For the second one, it’s 2*10^6

Answer:
x=13
Step-by-step explanation:
isolate the x by adding4 to each side of the equation
x - 4 = 9
+ 4 =+ 4
and then the -4 cancels out and you get x = 13
I hope this helps :)
