Answer:
x = 2
Step-By-Step Explanation:
It is really easy to see that the angle on the left side is almost equal to 90° (Right Angle) but is a bit less.
35 × 1 + 3 = 38 F It is too less than 90°
35 × 2 + 3 = 73 T It is closer and less than 90°
35 × 3 + 3 = 108 F It is close but more than 90°
35 × 4 + 3 = 143 F It is too much more than 90°
So,
x = 2
Double Checking
(180° - (35° × 2 + 3)) + (2 + 39°) + (3 + 30°)
= (180° - 73°) + 41° + 32°
= 107° + 41° + 32°
= 180°

Perimeter
2l + 2w = 27
l + w = 13.5
Area
l*w = 35
(35 / l) + l = 13.5
35 + l^2 = 13.5l
l^2 - 13.5l + 35 = 0
Using this equation, we can find the length first
then width can be found
Answer:
40 people
Step-by-step explanation:
Step one:
given data
let the total number of persons be x
There are 28 women
The number of men = 30% of x
Step two:
So the total person is given as
30/100*x+28= x
solve for x
0.3x+28= x
collect like terms
x-0.3x= 28
0.7x= 28
divide both sides by 0.7
x= 28/0.7
x= 40 people
64lb = 4 boxes
7*4= 28
64-28=36
Each bag of rice weighs 9 pounds
Here is your answer
C. 14x+2
REASON:
Given length of sides are:
3x+2, 6x and 5x
To find perimeter, add the length of three sides, i.e.
(3x+2)+6x+5x
=3x+2+6x+5x
...bring like terms together
=3x+6x+5x +2
=14x+2
