Answer:
The answer is - x² - 12x + 9
Step-by-step explanation:
1. Using (a-b)²= a²-2ab+b², expand the expression
2. Collect the like terms.
Answer:
So the question is asking you to write an expression which can be defined as a mathematical equation that contains two numbers (usually a <u>variable</u> represented by a letter from the english alphabet and a <u>constant</u> like 1, 2, 15, 73, or 10) and at the very least, one operation. So we are instructed to write an expression WITH an exponent. Examples of exponents would be squaring or cubing a number: 2² or 5³
With this kind of problem its more of a guess and check to try and see which numbers would make the equation true/equal to 24.
Here is an example of what I would put down:
24 = 3x³
24/3 = x³
8 = x³
2 x 2 x 2 = x³
2 = x
Check by plugging our x-value in:
24 = 3 x 2³
24 = 3(8)
24 = 24
Answer:

Step-by-step explanation:
y = 300x + 2200
Answer:
3 1/2 quarts
Step-by-step explanation:
The fraction of the lemonade that is water can be determined from the ratio of water to lemon juice. That fraction of a gallon is the quantity of interest.
<h3>Water fraction</h3>
Of the 7+1 = 8 parts that make up the lemonade, 7 of those are water. That is, water is 7/8 of the lemonade.
<h3>Water quantity</h3>
Of the 4 quarts of lemonade, the quantity that is water will be ...
(7/8)(4 quarts) = 7/2 quarts = 3 1/2 quarts . . . of water
