Answer:

Below.

Step-by-step explanation:

4X²+ 3x² - 6x + 8

Part A.

If x+3 is a factor then f(-3) = 0.

f(-3) = 4(-3)^3 + 3(-3)^2 - 6(-3) + 8

= -108 + 27 + 18 + 8

= -55

So x+3 is NOT a factor.

Part B.

We worked this out in Part A:

-55.

The volume of a cube is 64 cm3.

Rainbow [258]

Answer:

If the volume of a cube is 64 cm3, then the side length is 4 cm, because 4x4x4 = 64.

If the side length is 4cm, then the area of one side is 16cm2, and the surface area is 96cm2

A car travels 14km in 25mins . Find out how far the car can travel in 5 hours if the speed remains the same ?

jekas [21]

<h3><u>Answer :- </u></h3>

168 km ...

<h3><u>Explanation :- </u></h3>

It is given that the car travels 14km in 25 minutes..

Now , assume that the distance the car travel in 5 hours be x..

Since 1 hour = 60 minutes..
5 hours = 300 minutes ..

• Thus , The two given statements are :-

14km -----------------> 25 minutes..
And, x km -------------> 300 minutes..

The distance travelled by car and the time taken by the car is directly proportional to each other....

$\frac{14}{25} = \frac{x}{300}$

$= x = 168km$

• Hence , Car can travel 168km in 5 hours ..

Hope this helps you :)

Use the diagram to solve for the three variables so that the quadrilateral will be a rhombus. Show all of your work for full cre

satela [25.4K]

Answer:

x = 4
y = 4
z = 7

Step-by-step explanation:

Each triangle is a right triangle, and all are congruent. So ...

90 -m∠CAB = (1/2)m∠CDA

90 -(4x +33) = (1/2)(12x +34)

57 -4x = 6x +17 . . . . . . . eliminate parentheses

40 = 10x . . . . . . . . . . . . .add 4x-17

4 = x

We also have ...

2m∠CAD = m∠BCD

2(3z +28) = 10z +28

6z +56 = 10z +28 . . . . . eliminate parentheses

28 = 4z . . . . . . . . . . . . . .subtract 6z+28

7 = z . . . . . . . . . . . . . . . . divide by 4

Since BC = CD ...

x = y = 4

The values of the three variables are ...

x = 4, y = 4, z = 7.
