Answer:
- - 1 · (2×±5)
Step-by-step explanation:
8m - 5n + 2m + 6n =Simplifying
8m + -5n + 2m + 6n = 0
Reorder the terms:
8m + 2m + -5n + 6n = 0
Combine like terms: 8m + 2m = 10m
10m + -5n + 6n = 0
Combine like terms: -5n + 6n = 1n
10m + 1n = 0
Solving
10m + 1n = 0
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-1n' to each side of the equation.
10m + 1n + -1n = 0 + -1n
Combine like terms: 1n + -1n = 0
10m + 0 = 0 + -1n
10m = 0 + -1n
Remove the zero:
10m = -1n
Divide each side by '10'.
m = -0.1n
Simplifying
m = -0.1n.
You could reverse the triangle to look like a regular right triangle, making 7 on the bottom and 15 as the hypotenuse.
The height is about 13.2664991614216, which is rounded to 13
As long as we know the base and the hypotenuse we can calculate the value of x. If you do the math you get 62.181860715346076° which is rounded to 62<span>°
The answer is 62</span><span>°</span>
Answer:
<em>The width of the lid is 15 cm</em>
Step-by-step explanation:
<u>The Perimeter of a Rectangle</u>
Given a rectangle of width W and height H, the perimeter is calculated as:
P = 2(W + L)
Jon used 56 cm of ribbon to go around the edge of a rectangular lid. This means the perimeter is:
2(W + L) = 56
Dividing by 2:
W + L = 28
Since the lid was L=13 cm long, the width is:
W = 28 - 13 = 15
The width of the lid is 15 cm
