<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>We know that:</u>
- x = y
- 2(70 + 60) + x + y = 360
<u>Work:</u>
- 2(130) + x + x = 360
- => 260 + 2x = 360
- => 2x = 360 - 260
- => 2x = 100
- => x = 50
Hence, <u>the value of x is 50°.</u>
Hoped this helped.
Step-by-step explanation:
5x^2 - 20x + 20 = 5x^2 - 20x + 20
5(x^2 - 4x + 4) = 5(x^2 - 4x + 4)
(5 + 5) (x^2 - 4x + 4)
The answer is true. It does increase

Answer:
Step-by-step explanation:
The x intercepts occur when the quadratic is equal to zero.
1.
x^2-7x-18=0 factoring we get
(x-9)(x+2)=0 since multiplying anything by zero is zero the x intercepts occur when
x=-2 and 9
2.
2b^2+17b+21=0
2b^2+14b+3b+21=0
2b(b+7)+3(b+7)=0
(2b+3)(b+7)=0
b=-7 and -1.5
