Answer:
-3 + 4sqrt(2)
-3 - 4sqrt(2)
Step-by-step explanation:
(x – 4)(x + 10) = -17
FOIL on the left hand side (First outer inner last)
x^2 +10x-4x-40 = -17
x^2 +6x-40 =-17
Add 17 to each side
x^2 +6x-40+17 =-17+17
x^2 +6x -23 = 0
Using the quadratic formula
-b + - sqrt(b^2 -4ac)
-------------------------------
2a
where ax^2 +bx+c=0
-6 + - sqrt(6^2 -4*1*-23)
-------------------------------
2*1
-6 + - sqrt(36 +92)
-------------------------------
2
-6 + - sqrt(128)
-------------------------------
2
-6 + - 8sqrt(2)
-------------------------------
2
Divide top and bottom by 2
-3 + - 4sqrt(2)
-13 (q + 4) = 7q + 16
I think to solve it you do this first:
-13q + -52 = 7q + 16
And then I think you do:
-6q + -36
And thats all I can remember sorry ):
Or
That -6q + -36 might be the answer I think (:
Hope I could help (:
Answer:
A. the Commutative Property
Step-by-step explanation:
D doesn't exist
C is wrong and so is B.
In the given diagram, the measure of ∠3 will be 105°.
In the given diagram, ∠3 and ∠6 are consecutive interior angles.
<h3>How to form supplementary angles by transversal?</h3>
If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles formed are supplementary.
That is,
∠3 + ∠6 = 180°
From the given information,
∠6 = 75°
Then,
∠3 + 75° = 180°
∠3 = 180° - 75°
∠3 = 105°
Hence, the measure of ∠3 will be 105°.
