Answer:
Step-by-step explanation:
It is assumed PQS and RQS are similar triangles.
<u>The ratio of corresponding sides is equal:</u>
<u>Substitute side lengths and solve for x:</u>
- 15/(3x - 4) = 21/(5x - 16)
- 15(5x - 16) = 21(3x - 4)
- 5(5x - 16) = 7(3x - 4)
- 25x - 80 = 21x - 28
- 25x - 21x = 80 - 28
- 4x = 52
- x = 52/4
- x = 13
Answer:
The answer is attached as an image.
Step-by-step explanation:
- If we assume that the space is 100% of the population then:
88% have something and 12% have nothing.
So within the 88% there are 10% who have TV, 20% who have Radio and 58% who have both TV and Radio.
Step-by-step explanation:
4:3
4+3=7
4x + 3x= 7x
7x is the total sq.cm which is 300
7x= 300
x= 300/7
= 42.8
length= 4x
= 4 × 42.8
= 171.42
breadth= 3x
= 3 × 42.8
= 128.4
Answer:
(4x + 3)(3x - 2)
