Identify the factors of 9x^2+24x+16

Goryan [66]

Hi friend,

This is a perfect square trinomial.

It can be recognised because it is of the form:

a^2−2ab+b^2=(a−b)^2

with a=3x and b=4

9x2−24x+16=(3x)2−(2⋅(3x)⋅4)+42

=(3x−4)2

Evaluate x(y-z)2 for =-1,y=5,and z=

Nata [24]

Answer:

The value of $x(y-z)^2$ is -16.

Step-by-step explanation:

We need to evaluate $x(y-z)^2$ for x = -1, y = 5 and let us assume that z = 1

It can be simply done by putting the values of x,y and z in the given expression.

$x(y-z)^2=(-1)(5-1)^2\\\\=-1(4)^2$

We know that the value of 4² = 16

So,

$x(y-z)^2=16\times -1\\\\=-16$

So, the value of $x(y-z)^2$ is -16.

What the length of the hypotenuse

Free_Kalibri [48]

Answer:

73.43

Step-by-step explanation:

To find any hypotenuse use the Pythagorean theorem: $a^{2} +b^{2} =c^{2}$

First, square 36 (which would be 36 x 36) and square 64 (64 x 64).

Add them together.
Find the square root of the total.
That's your answer :)
