Step-by-step explanation:
all you need to do is distribute the 5 to everything in the parenthesis!
Answer:
y=3x^2 -15x-42
Step-by-step explanation:
Answer:
x = 4√2
Step-by-step explanation:
<u><em>Find the value of x. Leave your answer in simplest radical form. The chord measures 14, the diameter measures 18. Hint: use pythagorean theorem</em></u>
To solve, we will follow the steps below:
using Pythagoras theorem
opposite² + adjacent² = hypotenuse²
14² + y² = 18²
196 + y² = 324
subtract 196 from both-side of the equation
196 -196 + y² = 324-196
y² =128
Take the square root of both-side
√y² = √128
y =√128
y = √64×2
y =√64×√2
y = 8√2
x = half of y
x = y/2
x = 8√2 ÷ 2
x = 4√2
|x - 2x/5| <= 10
|5x - 2x| <= 50
3x <= 50
x <= 50/3
-|5x - 2x| <= 50
-3x <= 50
x >= - 50/3
answer
-50/3 <= x <= 50/3
The answer is 10x-5 hope this helps
