Fractions can't be added or subtracted if they don't have the same denominator. It doesn't have to be the least one, but they both have to be the same one. ... I can't think of a reason "why" that's short enough to type on an Android keyboard, but I'll give you this to think about: If I asked you to add 1/2. and. 1/5, and you didn't want to bother finding a common denominator, then what WOULD you use for a denominator for the sum ? ?
Step-by-step explanation:
We have:
x - y = 43 , xy = 15
To find, the value of x^2+y^2x
2
+y
2
= ?
∴ x - y = 43
Squaring both sides, we get
(x - y)^2(x−y)
2
= 43^243
2
⇒ x^2+y^2x
2
+y
2
- 2xy = 1849
Using the algebraic identity,
(a - b)^2(a−b)
2
= a^2+b^2a
2
+b
2
- 2ab
⇒ x^2+y^2x
2
+y
2
= 1849 + 2xy
Put xy = 15, we get
x^2+y^2x
2
+y
2
= 1849 + 2(15)
⇒ x^2+y^2x
2
+y
2
= 1849 + 30
⇒ x^2+y^2x
2
+y
2
= 1879
∴ x^2+y^2x
2
+y
2
= 1879

Answer: B.) 11 multiplied by 11 to the power of 4.
Step-by-step explanation:
11 to the 8th power divided by 11 to the 3rd power, or 11^8/11^3, equals 161,051. We are trying to find the option that has the same answer
A. is not the answer as it equals 1
C. is not the answer as it equals 0
and D. is not the answer is it equals 0 as well
The only correct option is B: 11 multipled by 11 to the power of 4, or 11 x 11^4, which equals 161,051

Hi there! The answer is £198.
If you spend 3 / 12 of a certain amount of money, you have 9 / 12 of the money left.
Simplify the fraction.
9 / 12 = 3 / 4.
To find the amount of money left, we multiply this factor by 264. We get the following
£264 × 3/4 = £264 × 0.75 = £198
Therefore the answer is £198
