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:
Step-by-step explanation:
To find the area of a rectangle you use the formula: A= lw
** l is length and w is width
For figure A and C, they're rectangles, so you multiply the length and the width to get the area:
Fig. A )A=lw
= (4)(4)
= 16
For figures B and D, you use the formula: A= bh/2
**B is the base and h is the height
Fig. D) A=bh/2
= 6(4)/2
= 12
Answer: True
Step-by-step explanation:
Answer:
Answer is C
Step-by-step explanation:
-3(2x - 4) is less than or equal to 7(3 - x)
-6x + 12 is less than or equal to 21 - 7x
x + 12 is less than or equal to 21
x is less than or equal to 9
