Answer:

$\bf \huge 12 \: inches$

Step-by-step explanation:

<h2>Given that :</h2>

a volume of 2880 cubic inches
a base of 240 inches

what is the height of a rectangular prism

<h2>formulas used :</h2>

height = volume ÷ base

<h2>explanation :</h2>

⟼ valume = 2880³ , base = 240 , height = ??

we know that,

height = valume ÷ base

<h2>finding the height :</h2>

⟼ height = valume ÷ base

⟼ height = 2880³ inches ÷ 240 inches

⟼ height = 12 inches.

∴ the rectangular prism height is 12 inches.

A gift box has a surface area of 6.25 square feet. What is the surface area of the box in square inches?

guapka [62]

The surface area of the box in square inches will be 39.0625 inches².

<h3>How to calculate the area?</h3>

From the information, the gift box has a surface area of 6.25 square feet.

Therefore, the surface area of the box in square inches will be:

= Side × Side

= 6.25 × 6.25

= 39.0625 inches²

Therefore, the surface area of the box will be 39.0625 inches².

Answer:

C) 6 feet

Step-by-step explanation:

The diagram is shown in the attachment.

Using the Pythagoras Theorem,

$x^2=4^2+4^2$

$x^2=16+16$

$x^2=32$

We take positive square root to obtain

$x=\sqrt{32}$

$x=4\sqrt{2}$

x=5.66ft

Rounding to the nearest feet we have x=6ft

A certain plant grows 134 inches every week. How long will it take the plant to grow 714 inches?

Bond [772]

The information we know:

1 week = 134 inches

x = 714

What I did was, I divided 714 by 134 to find the amount of weeks:

$714/134 = 5.3$

So, from the equation, basically, in 6 weeks (actually 5.3 weeks) the plant will grow 714 inches long

Answer:

x2 - 10x - 1994

Step-by-step explanation:

Step 1 :

Trying to factor by splitting the middle term

1.1 Factoring x2-10x-1994

The first term is, x2 its coefficient is 1 .

The middle term is, -10x its coefficient is -10 .

The last term, "the constant", is -1994

Step-1 : Multiply the coefficient of the first term by the constant 1 • -1994 = -1994

Step-2 : Find two factors of -1994 whose sum equals the coefficient of the middle term, which is -10 .

-1994 + 1 = -1993

-997 + 2 = -995

-2 + 997 = 995

-1 + 1994 = 1993

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

x2 - 10x - 1994
