Answer:
x = -1 ± √6
Step-by-step explanation:
Lets use the quadratic formula →
So ,
Lets take 2 common from numerator.
Cancelling 2 from numerator & denominator gives
Answer:
<h2>
Perimeter = 2x² + 16x + 6</h2><h2>
Area = 6 x² + ¹/₂x - 3</h2>
Step-by-step explanation:
The perimeter = a + b + c + d
= (6x + 4) + (2x² + 5x - 3) + (-3x - 6) + (8x + 11)
= 2x² + 16x + 6
The area = [(a + b) ÷ 2] h
= [((6x + 4) + (-3x - 6)) ÷ 2] (4x + 3)
= [(3x - 2) ÷ 2] (4x + 3)
= (³/₂x - 1) (4x + 3)
= 6 x² + ¹/₂x - 3
Answer: y = -3
<u>Step-by-step explanation:</u>
-8x - 5y = -1

= -3
Answer:
x = 115
Step-by-step explanation:
If lines are parallel, alternate interior angles are congruent (the same measure). Since this is a parallelogram, opposite sides are parallel, and AIA is applicable, so x = 115 degrees.
