Answer:
a. x = 7; b. 75
Step-by-step explanation:
Equilateral means all sides equal the same measurement
4x - 3 = 2x + 11
4x - 2x = 11 + 3
2x = 14
x = 7
Plug in x = 7 to any equation
4(7) - 3
28 - 3
25
Perimeter means add up all 3 sides
25 + 25 + 25
75
The answer is C) 7.
In function 1, there is no rate of change.
In function 2, there is a rate of change of 7.
This leaves 7 as the only possible answer.
Answer:
a. x=11°
b. ABC=106°, BCA=33° and BAC=41°
c. Sorry but I can't see the lines l and m
Step-by-step explanation:
a. the question stated that the sum of the measures of the angles in the triangle is 180°
so therefore equate all the values in the triangle to 180°
(9x+7)+ 3(x) + (3x+8)=180°
15x+ 15=180
15x=180-15
15x=165
Divide both sides by 15
therefore x=11
b. ABC=(9x+7)
where there is x put the x value you solved for there which is 11
therefore ABC=(9×11+7)= 106°
Do the same for BCA and BAC
Answer:
The kinetic energy will increase.
Step-by-step explanation:
1/2*80*9=360J .After the acceleration, it will increase to 1/2*80*36=1440J
answer = 2
