multiply the binomials:
(x + 3y) (3x - 2y)
Answer:
Simplify the expression:
3x^2+7xy−6y^2
Steps:
3x·2+7xy-6y·2
Multiply the numbers: 3·2=6
=6x+7xy-6·2y
Multiply the numbers: 6·2=12
=6x+7xy-12y
Answer:
x = 2
Step-by-step explanation:
The sum of the 3 angles in the triangle = 180°
Sum the 3 angles and equate to 180
6x + 15 + 90 + 63 = 180
6x + 168 = 180 ( subtract 168 from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
Answer: Vertical angles are congruent.
Step-by-step explanation:
In the given picture, NS and RT are intersecting line segments, intersects at point Q.
We know that when two lines intersect to make an cross, angles on opposite sides of the cross are called vertical angles. These angles are equal by the theorem that says Vertical angles are congruent.
⇒∠NQT ≅ ∠SQR
Therefore, the reason that justifies the step 2 :- ∠NQT ≅ ∠SQR is "Vertical angles are congruent" in the proof.
I believe the Answer is A
