Answer:
8 1/6 < x < 20.5.
Step-by-step explanation:
Use the Triangle Inequality Theorem which states that the sum of any 2 sides of a triangle is always greater that the third side.
So for triangle to be formed:
4x + 2x - 4 > 45
6x > 49
x > 8 1/6.
Also 2x - 4 + 45 > 4x
41 > 2x
2x < 41
x < 20.5.
First solve the first equation to find x.
x-5=2
x=7
Now plug it in to the other equation to get your answer.
6(7)-20
42-20
22
The answer is 22.
The area is 60m squared.
The formula for a triangle is base times height, divided by 2. Base times height in this case is 10m x 12m, which is 120m. 120m divided by 2 is 60m squared. (It is squared because it is not just a length, but an area of a flat shape.)
Answer:
.125
Step-by-step explanation:
The volume of a cube is found by
V = s^3 where s is the side length
V = .5 ^3
V =.125 m^3
The answer is 4+8+16+32+64+128+256+512+1024: This is equivalent to 2044
