1 answer:

7 0

If the bold numbers and variables are 2x + 5, then those would be B. addend, or the numbers that are added. Minuend is the number from which you subtract.
And since there is no dividing here, C or D are incorrect.

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.

What is the area of the deck, not including the garden, in Plan A? (Type

zalisa [80]

Answer:

342 ft squared

Step-by-step explanation:

You know how to find the area of a rectangle: Multiply the dimensions together (length x width).

You can also see that the garden is inside the deck, and that it is also a rectangle. Therefore, you can find the area of the deck ONLY by subtracting the area of the small rectangle from the big one.

First, find the area of the big rectangle:

18 * 25 = 450 ft squared

Now, find the area of the small one:

9 * 12 = 108 ft squared

Finally, subtract the area of the small rectangle from the area of the big one:

450 - 108 = 342 ft squared

Hope this helps! Please comment on this answer if you have any questions :)

Find the value of f (x)=x²-4 and g(x)=3x+2 Find the value of f (-1)g(-1)

mrs_skeptik [129]

Answer:

Step-by-step explanation:

$f(-1)g(-1) \text{ is the same thing as } f(-1)\cdot g(-1). \\\text{Therefore, find f(-1) and g(-1)}$

$f(-1)=(-1)^2-4\\f(-1)=1-4\\f(-1)=-3$

$g(-1)=3(-1)+2\\g(-1)=-3+2\\g(-1)=-1$

Therefore:

$f(-1)\cdot g(-1)\\=(-3)(-1)=3$
