Answer:
length=11 width=10
Step-by-step explanation:
Create two equations with length(l) and breath(w) as our unknowns
2l+2w=42
2l=42-2w
2l/2=(42-2w)/2
l=21-w(equation 1)
lxw=110
lw=110
Substitute equation one into equation two
(21-w)w=110
21w-w²=110
Write your equations in standard quadratic form
0=w²-21w+110
solve this as a quadriatic tri nominal
0=(w-10)(w-11)
0=w-10. or 0=w-11
10=W. 11=L
Answer:
Step-by-step explanation:
This is actually a very important question and it is very subtle. Let's just take an ordinary segment.
Suppose we have a segment that is this long
=========o=========
The segment up to the o is nine equal signs long.
The segment after the o is also nine equal signs long.
Here's the crunch. Since they are equal, the ratio is 1 to 1. The segment is divided in half.
Now take the second half of the question.
======o============
The left side of the o is 6 equal signs long.
The right side of the o is 12 equal signs long.
The ratio is 1:2. There are still 18 equal signs but now they are divided as 6/12 which is not the same thing as 9/9
Very interesting question.

Answer:
Step-by-step explanation:
We have two congruent right triangles and three rectangles.
First, calculate the length of the hypotenuse using the Pythagorean theorem:
We have
Substitute:
The formula of an area of a right triangle:
Substitute:
The formula of an area of a rectangle:
w - width
l - length
Rectangle 1:
w = 15, l = 22
Rectangle 2:
w = 17, l = 22
Rectangle 3:
w = 8, l = 22
The Surface Area of the triangular prism:
Substitute:
Answer:
x = 35°
Step-by-step explanation:
assuming that the straight line at the bottom of the figure is actually a straight line, that means all the angles along that straight line must add up to 180 °
i.e.
40 + (2x+30) + 40 = 180
40 + 2x+30 + 40 = 180
110 + 2x = 180 (subtract 110 from both sides)
2x = 180 - 110
2x = 70
x = 35
