Answer:
False
Reasoning:
- It's an acute angle, 140 is obtuse
- Angles 6 and 8 are 140 degrees, so 5 can't be
It's the first choice. 9b = 11.07.
Answer: A)Area=1/2bh, 1/2x12x9=1/2x108,108/2=54cm2.
B)If the base doubles the original Area doubles.
C)If both the Height and the base is doubled then the Area will Quadruple.
Step-by-step explanation:
Convert the first to an equation:
6(x+15)=-42
6x+90=-42
6x=132
x=22
Same for second equation:
4(x-7)=12
4x-28=12
4x=40
x=10
The solutions are x=22 and x=10
