Answer:
16.666% would be flawed.
Step-by-step explanation:
Alright.
For 7, you'll want to put congruent sides equal to each other, assuming they are parallelograms. So, you'll get the two equations:
3x+2=23
2y-7=9
Solve using GEMDAS/PEMDAS, and you'll get these answers.
3x+2=23
3x=21
x=7
2y-7=9
2y=2
y=1
For 8, you'll want to do the exact same thing, formatting the numbers to equal each other. You'll get these two equations:
3y+5=14
2x-5=17
Solving them would make:
3y+5=14
3y=9
y=3
2x-5=17
2x=22
x=11
For 9, you have to remember that the angle opposite of one angle in a defined parallelogram are congruent. Thus:
130=2h
5k=50
solve them and you get
h=65
k=10

Answer: 10u3 + 4u2 - 2u + 10
Step-by-step explanation:
( 4u3 + 4u2 + 2) + ( 6u3 - 2u + 8)
opening the bracket
4u3 + 4u2 + 2 + 6u3 - 2u + 8
collecting like terms
4u3 + 6u3 + 4u2 - 2u + 2 + 8
10u3 + 4u2 - 2u + 10
Answer:
x < -15
Step-by-step explanation:
-1x + 5 < 20
- 5 - 5
-1x < 15
/-1 /-1
x < -15
