Answer:
The zeros of the polynomial are x = 7 or x = -11/2
Step-by-step explanation:
The zeros of a polynomial refers to the solution of the polynomial.
6x^2 + 19x -77
6x^2-14x+ 33x -77
2x(x-7) + 11(x-7)
= (2x + 11)(x-7)
2x + 11 = 0
x-7 = 0
2x = -11
x = -11/2 = -5.5
and x-7 = 0
x = 7
So the zeros of the polynomial are x = 7 or x = -11/2
Answer:
37/50
Step-by-step explanation:
74/100
37/50
Answer:
Step-by-step explanation:
<u>The new dimensions will be:</u>
The area is 540
<u>Using area equation we get:</u>
- (10 + x)(22 + x) = 540
- x² + 32x + 220 = 540
- x² + 32x = 320
- x² + 2x*16 + 256 = 320 + 256
- (x + 16)² = 576
- x + 16 = √576 (Ignoring the negative root as the length is never negative)
- x + 16 = 24
- x = 8
<u>The new dimensions are:</u>
- 10 + 8 = 18 ft and
- 22 + 8 = 30 ft
Guessing these are the options:
4 + (-8) ___ 6 + (-8) + (-6)
If the signs are the same, you add. If you have one positive and one negative sign, you minus:
4 + (-8) = 4 - 8 = -4
6 + (-8) = 6 - 8 = -2
(-2) + (-6) = (-2) - 6 = -8
-4 ___ -8
<h2>-4 > -8</h2>
1st possibly the number line
2nd you can draw them on paper
3rd try them at percentage
