How many square inches in a foot

Mathematics
1 answer:
Cloud [144]3 years ago
5 0

Answer:

There are 144 square inches in a square foot.

Step-by-step explanation:

A square foot is a square that is 1 foot by 1 foot. Since there are 12 inches in 1 foot, and to get the area you need to multiple 2 adjacent sides together, you do 12 times 12 which is 144 square inches. Many people have the misconception that a square foot has 12 square inches, but this is wrong since a square foot has dimensions of 12 inches by 12 inches, but when you multiply them together, you can see that the answer is actually 144.

Simplify: 3x^2-8x+4 and show work please
Bad White [126]

believe what you're asking is to turn the trinomial into two binomials

So you first have to get 3x²; the only way to get this is

(3x    )(x     )     when multiplying that, you would get 3x²

when dealing with the -8x and the 4, you must find numbers that are factors of four (when multiplied together they will equal 4) and will multiply with the x's to get -8

(3x-2)(x-2)

you can tell that this is the answer because when you multiply though you will get:

3x-2x²-6x+4

or: 3x²-8x_4

Hope this helped

The sum of the digits of a two-digit number is 8. The difference between the number and the reversed number is 10 more than the
Vesna [10]

Answer:

The number is 62

Step-by-step explanation:

Let the digits of the number be T and U;

A 2 digit number is represented as: 10T + U

So,

T + U = 8

10T + U - (10U + T) = 10 + 10U + T

Required

Find the digit

Make U the subject in the first equation

U = 8 - T

Substitute 8 - T for U in the second

10T + U - (10U + T) = 10 + 10U + T

10T + 8 - T - (10*(8-T) + T) = 10 + 10(8 - T) + T

10T + 8 - T - (80-10T + T) = 10 + 80 - 10T+ T

10T + 8 - T -80+10T - T = 10 + 80 - 10T+ T

Collect Like Terms

10T + 10T - T- T + 8  -80 = 10 + 80 - 10T+ T

18T -72 = 90 - 9T

9T + 18T  = 90 + 72

27T  = 162

T = 162/27

T = 6

Recall that:

U = 8 - T

U = 8 - 6

U = 2

<em>Hence, the number is 62</em>
