Answer: -1 84/135
Step-by-step explanation:
- 8/9 (15) + 11/15(9)
= - 120/135 + 99/135
=219/135
= - 1 84/ 135

Area of a Triangle = 1/2 * bh
A = 1/2 * 6 * 8
A = 1/2 * 48
A = 24
In short, Your Answer would be Option A
Hope this helps!
Answer:
75 percent i think
Step-by-step explanation:
<span>Given the following statements and Reasons
1. WXYZ is a ▱; ZX ≅ WY 1. given
2. ZY ≅ WX 2. opp. sides of ▱ are ≅
3. YX ≅ YX 3. reflexive
4. △ZYX ≅ △WXY 4. SSS ≅ thm.
5. ∠ZYX ≅ ∠WXY 5. CPCTC
6. m∠ZYX ≅ m∠WXY 6. def. of ≅
7. m∠ZYX + m∠WXY = 180° 7. ?
8. m∠ZYX + m∠ZYX = 180° 8. substitution
9. 2(m∠ZYX) = 180° 9. simplification
10. m∠ZYX = 90° 10. div. prop. of equality
11. WXYZ is a rectangle 11. rectangle ∠ thm.
The missing reason in step 7 is "</span><span>consecutive ∠s in a ▱ are supplementary"</span>
6a²-12a+36= 6a²-12a=-36
Put the normal number on the other side to have the variables on one side, and the normal number on the other.
Then group:
= 36a-12a= -36
= 24a=-36
Then isolate a:
= a=-36/24
Then simplify:
=a = - 3/2
