Answer: A)x²+x-6 B) 2x²-13
Step-by-step explanation: A) (x+3)(x-2)(x-8) = x²-2x+3x-6 = x²+x-6
B) (x+2)(x-2)(x+3)(x-3) =→ x²-2x+2x-4 = x²-4
→x²-3x+3x-9 = x²-9
∴x²-4+x²-9 = <u><em>2x²-13</em></u>
Answer: The answer could be C because is the image of the rotation by 90 degrees clockwise. I hope its right
Answer:
Step-by-step explanation:
<u>Let the number is x, then we have:</u>
- 6x - 19 = 4x + 11
- 6x - 4x = 11 + 19
- 2x = 30
- x = 15
Answer:
x≤50
Step-by-step explanation:
100-3x≥-50
subtracting 100 at both side on inequality
-100+100-3x≥--50-100
-3x≥-150
Dividing both sides by 3
-3x/3≥-150/3
-x≥--50
Adding 50 on both sides
-x+50≥-50+50
-x+50≥0
Adding x on both sides
-x+x+50≥0+x
50≥x
so,
x≤50
