Answer:
A
Step-by-step explanation:
x² + 10x + 24 = 0
Here, a = 1, b = 10, c = 24. Factoring using the AC method:
ac = 1×24 = 24
Factors of 24 that add up to 10 are +4 and +6.
Therefore:
(x + 4) (x + 6) = 0
x + 4 = 0, x + 6 = 0
x = -4, x = -6
The roots are -4 and -6. Added together:
-4 + -6 = -10
Answer A.
40.) 10.5^2 and the area is 110.25
41.) 126
42.) 81 millimeters
8n = -3m + 1
n = -2, 2,4
first add -2, 2 and 4 which = 4
then do 8(4) = -3m +1 which makes 24 = -3m +1 so subtract 1 on both sides then you have 23 = -3m divde -3 on both sides which equal -7.66 or 8
11-3 =8
19-11 = 8
27-19= 8
35-27 =8
the common difference is 8
Answer:
∠4 and ∠6
Step-by-step explanation:
we know that
<u>Alternate interior angles</u> are two interior angles which lie on different parallel lines and on opposite sides of a transversal
In this problem
m∠3=m∠5 --------> by alternate interior angles
m∠4=m∠6 --------> by alternate interior angles
therefore
<u>the answer is</u>
∠4
and
∠6
