25 , 36 and 49
5^2= 25
6^2= 36
7^2= 49
Answer:
-7.8k - 7.2
Step-by-step explanation:
Distribute 0.6 to the terms in the parentheses:
0.6(-13k - 12)
-7.8k - 7.2
So, the simplified expression is -7.8k - 7.2
Answer:
15 ft
Step-by-step explanation:
using geometry, we can find that the triangles are proportional, so if 8:24::5:15. 24/8=3, so do 5×3
22)
Because OP and OR trisect <NOS
so <NOP = <POR
3x - 4y = x - y so 2x = 3y
<POR = <ROS
x - y = y - 10 so x = 2y - 10
Substitue x = 2y - 10 into 2x = 3y
2(2y - 10) = 3y
4y - 20 = 3y
y = 20
x = 2y - 10 = 2(20) - 10 = 30
x = 30 and y = 20
<ROS = y - 10 = 20 - 10 = 10
Answer
<ROS = 10°
