49–2ax –a^2–x^2
Extract the negative sign
= 49 - (a^2 +2ax +x^2)
Factor using a^2 + 2ab + b^2 = (a+b)^2
= 49 - (a+x)^2
Factor using a^2 - b^2 = (a-b)(a+b)
= ( 7- (a + x)) * (7 + (a + x))
= ( 7- a - x) * (7 + a + x)
Answer:
- 3 ≤ x < 0
Step-by-step explanation:
- 3 is included in the set thus x can equal - 3
- 3 is less than all other values in the set including the largest value of 0, thus
- 3 ≤ x < 0
Y = 2x
I think that's what you're asking
Answer:
Option (A)
Step-by-step explanation:
By the property of a parallelogram,
Opposite sides of a parallelogram are equal and parallel to each other.
AD = BC and DC = AB
9x - 40 = 8x - 34
9x - 8x = 40 - 34
x = 6
4y + 20 = 6x - 4
4y - 6x = -24
2y - 3x = -12
Now we will substitute the value of x,
2y = 3x - 12
2y = 3(6) - 12
2y = 6
y = 3
Therefore, Option (A) will be the correct option.
