True or false 120% of a whole number is always greater than the number? and why?

Stells [14]

I can only use math to explain it. What is 100%?
100% = $\frac{100}{100}$
percent means per 100.
so 120% = 120/100 = 1.2
120% of a whole number. For example 120% * 10 = $\frac{120}{100} * 10$ = 12
is it greater than 10.

Complete the square to transform the expression x2 + 4x + 2 into the form a(x − h)2 + k.

Nina [5.8K]

Answer:

Step-by-step explanation:

y = (x^2 + 4x) + 2

Take 1/2 of the linear term 4/2 = 2 and square that result. 2^2 = 4.

Put it after 4x

y = (x^2 + 4x + 4) +2 Subtract what you put inside the brackets on the outside.

y = (x^2 + 4x + 4) + 2 - 4 Combine the right.

y = (x^2 + 4x + 4) - 2 Express the brackets as a square.

y = (x + 2)^2 - 2

That's your answer

a = 1

h = 2

k = -2
