13. $9 because 75%=3/4 and 1/4 of 12 is 3, and so you multiply $3 by 3 to get $9
14. Multiply 325 by .2 to get $65.00
15. 15 minutes, because if it rises 2 feet every hour, then it rises 1 foot every hour, and so you divide that by 2 to get 15
Answers:
13. $9
14. $65.00
15. 15 mins
The new triangle is gonna be bigger. But how big? Let’s look at A.
A= 2,8
Look at A’, it’s 6,24. See a pattern??
Multiply 2,8 by 3. It’s triple the amount, therefore the scale factor is 3.
To double check, multiply by 3 to B and C and see what you get.
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
Answer:
The length is 5/6 yard.
Also make sure you try out the promblem before just going here and taking answers it's not fair or right stop try first.
The answer should be the first one, 2. Do you need and explanation?
4x+y/2y-x
Start by replacing all of the variables.
4(2)+4/2(4)-2
Now work multiply.
8+4/8-2
Now add.
12/6
That is your fraction. But you must simplify it.
Its simplifies to 2.
