Answer:
the value of x is 14.56
Step-by-step explanation:
by using Pythagorean theorem
x²=13.6²+5.2²
x²=212
x=14.56
Answer:
2x³- 2px² + p + 2
First plug in x = -3
2(-3)³- 2p(-3)² + p + 2
According to PEMDAS, we should solve the exponents first.
(-3)³ = -27
(-3)² = 9
2(-27) - 2(9)p + p + 2
Now multiply.
-54 - 18p + p + 2
Now combine the variables and constants.
-17p - 52
This is the simplified expression.
If it is an equation, then it would equal 0.
-17p - 52 = 0
To solve for p, add 52 to both sides.
-17p = 52
Now isolate the p by dividing by -17.
p = -52/17 or -3.0589
Answer:
The correct answer would be obtuse
Step-by-step explanation:
An obtuse angle is an angle that has a measure of more than 90°
So if a triangle has an angle greater than 90° it would be classified as an obtuse triangle
Answer:
31
Step-by-step explanation:
5*6+1
30+1
31
The notation is a little sketchy, but I think you mean f(x)*g(x), right?
We'll use the substitution property of equality. This states that for any x and y, if x = y, then we can use y in place of x, or x in place of y as needed.
Since f(x) = 2x + 5, we can replace f(x) with 2x + 5. We can also replace g(x) with 3x - 4.
To find f(x) * g(x), make the necessary replacements:
f(x) * g(x)
=(2x + 5)*(3x-4). Now FOIL it out:
=6x2 -8x + 15x - 20
=6x2 + 7x - 20. Right
