Answer:
Your answer would be 6, -4, and 3
Step-by-step explanation:
Answer:
it is c option 50 degree it must
A = lw
80 = 2x(x - 3)
80 = 2x(x) - 2x(3)
80 = 2x² - 6x
0 = 2x² - 6x - 80
0 = 2(x²) - 2(3x) - 2(40)
0 = 2(x² - 3x - 40)
2 2
0 = x² - 3x - 40
0 = x² - 8x + 5x - 40
0 = x(x) - x(8) + 5(x) - 5(8)
0 = x(x - 8) + 5(x + 8)
0 = (x + 5)(x + 8)
0 = x + 5 or 0 = x + 8
- 5 - 5 - 8 - 8
-5 = x or -8 = x
The values of x are -5 and -8.
a:
Just divide both sides by 7. Since 7 is positive, you don't need to change the inequality sign:
![7j>77\iff j>11\}](https://tex.z-dn.net/?f=7j%3E77%5Ciff%20j%3E11%5C%7D)
In set notation, we write
![\{j \in \mathbb{R}\ :\ j>11](https://tex.z-dn.net/?f=%5C%7Bj%20%5Cin%20%5Cmathbb%7BR%7D%5C%20%3A%5C%20j%3E11)
b:
Subtract 9 from both sides:
![17\leq x+9 \iff 8\leq x](https://tex.z-dn.net/?f=17%5Cleq%20x%2B9%20%5Ciff%208%5Cleq%20x)
In set notation, we write
![\{x \in \mathbb{R}\ :\ x\geq 8\}](https://tex.z-dn.net/?f=%5C%7Bx%20%5Cin%20%5Cmathbb%7BR%7D%5C%20%3A%5C%20x%5Cgeq%208%5C%7D)
