Answer:
10
Step-by-step explanation:
This triangle is isosceles, same as the little triangle.
If one side of the little triangle is 3x, then the little side with the tick (let's name it a) is also 3x.
That means the longer side, 2a, is 6x
This triangle is isosceles, so 6x = 4x + 20
Now, if we solve that, x = 10
The answer is 10
Hope this helps :)
Have a good day!
Answer:
<em>f = g/ g+1</em>
Step-by-step explanation:
Remove Parenthesis.
<em>fg - 1 x 5 = g - 1 x f - 1 x 5</em>
Cancel <em>-1 x 5</em> on both sides.
<em>fg = g - 1 x f</em>
Simplify <em>1 x f</em> to f.
<em>fg = g - f</em>
Add <em>f </em>to both sides.
<em>fg + f = g</em>
Factor out the common term <em>f.</em>
<em>f (g + 1) = g</em>
Divide both sides by <em>g + 1</em>
<em>f = g/ g + 1</em>
Is the the line veritcal or horizontal,if its vertical then the slope is undefined, if its horizontal then it should be zero leading to y=4÷9 or y=0.44
Answer:
length = 16m
width = 4m
Step-by-step explanation:
1. if the length is 4 times the size of the width then we can call the width x and the length is 4x
2. make an equation 4x + 4x + x + x = 40m
3. solve the equation 10x = 40 x = 4
4. width = x width = 4m length = 4x length = 16m
5. check this 16 + 16 + 4 + 4 = 40
