Evaluate

Mathematics
1 answer:
Montano1993 [528]3 years ago
3 0

Step-by-step explanation:

Multiplication of fractions is easiest operation. Simply multiple numerator to numerator and denominator to denominator. For example,

\frac{x}{y} * \frac{a}{b }= \frac{x*a}{y*b}

Addition and subtraction requires that we find a common demoninator.

For example,

\frac{6}{4} + \frac{4}{3}

The common denominator is 12. So I need to muliply each fraction to get the right denominator. 4*3 = 12.

\frac{6}{4}*\frac{3}{3} + \frac{4}{3} \frac{4}{4} = \frac{18}{12}+\frac{16}{12}

Then we add the numerators

\frac{18+16}{12} = \frac{32}{12}

Then we should reduce.

\frac{16}{6} = \frac{8}{3}

Division is a little trickier because we have to flip-flop the second term and then multiply. For example: \frac{1}{10} \div \frac{5}{6} \rightarrow \frac{1}{10} * \frac{6}{5} = \frac{6}{50}

What is the surface area?<br>What is the surface area of G​
myrzilka [38]

Answer:

226 cm^2

Step-by-step explanation:

It’s literally a rectangular prism If you put it together. The side with 2 cm and 11 cm , the surface area is 22 and since this is a rectangular prism, that means there is a second of the same kind. Then you get the larges box, since you know that the top side is 11 and the left side is 7, you multiply that * 2 which you then get 154. You add that up with the side that you solved before so 154 + 44 = 198. You then figure out the left side 7 * 2 * 2 (because there are two of them). 28 + 198 = 226 cm^2.

The sum of the squares of two consecutive integers is 145. Find the two integers.
worty [1.4K]

Answer: The two integers are 8 and 9.

Step-by-step explanation: Let n represent the number.

n^2 + (n + 1)^2 = 145

By foiling, this can be rearranged to:

n^2 + n^2 + 2n + 1 = 145

Subtract 145 from both sides:

2n^2 + 2n - 144 = 0

Divide both sides by 2:

n^2 + n - 72 = 0

Factor the polynomial:

(n + 9)(n - 8) = 0

Solve for n:

n = -9, n = 8

Since they need to be consecutive, make the 9 positive. It will be positive either way because it is being squared.

Now, n = 9 and n = 8.

These are your two integers. Hope this helps!
