Answer:

Nalani is correct.

Step-by-step explanation:

Given - Nalani says the expression 9+7r cannot be factored using the GCF.

To find - Is she ​correct? Explain why or why not.

Proof -

GCF - Greater Common factor

Given that, the expression is - 9 + 7r

As

HCF(9, 7) = 1

So , we can not factor the expression.

i.e. there does not exist any number who is a multiple of 9 and 7 both.

So,

Nalani is correct.

Example -

Let the expression be 24 + 18x

HCF(24, 18) = 6

So,

24 + 18x = 6(4 + 3x)

Find the area of the parallelogram by finding the height of the 45 45 90 triangle
slavikrds [6]

Answer:

45 in²

Step-by-step explanation:

Since it's a 45-45-90 triangle, the legs are equal length.  The legs are the sides that are not the hypotenuse.  The hypotenuse is the side opposite the 90° angle.  Here, the legs are both 6.  This is also the height of the parallelogram.  

The formula for area of a parallelogram is

A = LH    where L is the side length, and H is the height

So the area is

A = 7.5(6) = 45 in²

Number 25 someone help me
Fittoniya [83]
The area of a triangle is given by the formula A= \frac{1}{2}Bh, where B is the base and h is the height. We can rearrange this formula to solve for B.

\dfrac{A}{ \frac{1}{2}h} = B\\ \\\\\dfrac{2A}{h} = B.

We plug in the given area, 640 square millimeters, and the given height, 32 millimeters.

B= \dfrac{2(640)\ mm^2}{32 \ mm} = 40 \ mm.

40 mm is our final answer.

A ball is thrown into the air with an upward velocity of 36 ft/s. It’s height h in feet after t seconds is given by the function
777dan777 [17]

Answer:

Time taken for the ball to hit the ground back = 3.08 s

Step-by-step explanation:

h(t)= -16t² + 48t + 4

when will rhe object come back to hit rhe ground?

When the ball is at the level.of the ground, h(t) = 0.

0 = -16t² + 48t + 4

-16t² + 48t + 4 = 0

Solving the quadratic equation

t = 3.08 s or t = -0.08 s

Since the time cannot be negative,

Time taken for the ball to hit the ground back = 3.08 s

Hope this Helps!!!
