The answer to this question would be: L= 33.5, W=33.5
In this question, the rectangle has a perimeter of 134. From this number, you can get this equation:
perimeter=134
2(L+W)= 134
L+W=67
L= 67-W
Using the formula for dimension you can get this equation:
dimension= L * W
dimension= (67-W)W= 67W- W^2
The maximum dimension should be differentiation of the equation which will look like:
67 -2w= 0
2w= 67
w= 33.5
Triangles equal a total of 180°. Add the angles together equal to 180°.
x= unknown angle
x + 13° + 154°= 180°
x + 167= 180
subtract 167 from both sides
x= 13°
ANSWER: x=13° which means this is an isosceles triangle with two equal angles of 13°.
Hope this helps! :)
8x^3 + 1 = 0
8x^3 = -1 <----------- Step 1: Subtract 1 from both sides.
x^3 = -1/8 <----------- Step 2: Divide both sides by 8.
x = ∛(-1/8) <----------- Step 3: Cube root both sides
x = -0.5 <----------- This is the final answer when you plug the last step into the calculator
We set up a proportion: 80/?= 32/100
Cross multiply: 32*?= 80*100
⇒ ?= 80*100/32= 250
80 is 32% of 250.
