Answer:

Step-by-step explanation:

Evaluate the expression if x = 3 and y = 6.

4x + 3y

The value of x is 3 and the value of y is 6

The given expression is $4x+3y$

Now we plug in the value of x and y in the given expression

$4x+3y$

$4(3)+3(6)$

$12+18=30$

So the value of the given expression is 30

Here, Just substitute their values,
4x + 3y
= 4(3) + 3(6)
= 12 + 18
= 30

In short, Your Answer would be 30

Hope this helps!

Jada is using 84 one-centimeter cubes to build a rectangular prism. She wants the height of the rectangular prism to be 4 centim

Black_prince [1.1K]

Answer:

One rectangular prism is possible with 7cm × 3cm × 4cm.

Step-by-step explanation:

Jada used number of cubes = 84

Side of one small cube = 1 cm

Volume of one small cube = 1 cm³

Volume of 84 small cubes = 84 cm³

She wants to build a rectangular prism with height = 4 cm

Let the length of the prism = x cm

and the width of the prism = y cm

and x > y

Volume of the prism = length × width × height

= (x)(y)(4)

= 4xy cm³

If the volume of prism = volume of 84 small cubes

Then 4xy = 84

xy = 21

Possible values of x = 3, 7

and y = 7, 3

But x > y

So x = 7 and y = 3 will be the answer.

Therefore, only one rectangular prism is possible with dimensions

length = 7 cm, width = 3 cm, height = 4 cm.
