The answer that I had gotten to my answer was the third one.
Answer:
x²-10x+25
Step-by-step explanation:
f(x) = x²
<h3>i) substitute the x-5 into x</h3>
f(x-5) = (x-5)²
<h3>ii) using the formula (a-b)² = a²-2ab+b², expand the expression</h3>
f(x-5) = (x-5)²
= x²-2(5x)+5²
<h3>iii) calculate the products</h3>
f(x-5) = x²-2(5x)+5²
= x²-10x+25

The sum is composite because it is the same as multiplying the number by two.
Answer:
–7 is not the arithmetic square root of 49 only in case we are taking it for natural number.
Step-by-step explanation:
- The square root of x is that number which on squaring gives the result as x.
- For example, the square root of 4 is +2 or -2. Because on squaring +2 or -2 we get the number 4.
- Similarly for the case of 49, the square root might be both +7 or -7.
- But if we are taking it as a natural number then -7 is not valid. Like for length, quantity or other sort of things -7 is not the arithmetic square root of 49.
Answer:
2
Step-by-step explanation:
if you work inside parentheses first you get:
4^3/2 ÷ 4^1/2 which is 4
4^1/2 = 
which is 2
