Answer 1
Answer:

The expression is equivalent to x^4 - 12x^2 + 36 is (x^2 - 6)(x^2 - 6) correct.

We have given that

x^4 - 12x^2 + 36

We have to determine

Which expression is equivalent to x^4 - 12x^2 + 36.

What is the equivalent expression?

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).

(x^2 plus or minus 6)(x^2 plus or minus 6)

an easy way to do this is to only look at plus or minus 6

x^4 - 12x^2 + 36   (-12 and 36)

6 x 6 = 36

6 + 6 ≠ -12            

(x^2 + 6)(x^2 + 6) is incorrect      

6 x -6 ≠ 36

6 + -6 ≠ -12            

(x^2 - 6)(x^2 + 6) is incorrect

-6 x -6 = 36

-6 + -6 = -12      

Therefore the option (x^2 - 6)(x^2 - 6) is correct

The expression is equivalent to x^4 - 12x^2 + 36 is (x^2 - 6)(x^2 - 6) correct.

Answer 2
Answer: so the answer is
(x^2 plus or minus 6)(x^2 plus or minus 6)
an easy way to do this is to only look at plus or minus 6
x^4 - 12x^2 + 36   (-12 and 36)

6 x 6 = 36
6 + 6 ≠ -12              (x^2 + 6)(x^2 + 6) is incorrect        

6 x -6 ≠ 36
6 + -6 ≠ -12             (x^2 - 6)(x^2 + 6) is incorrect

-6 x -6 = 36
-6 + -6 = -12         (x^2 - 6)(x^2 - 6) is correct

the answer is (1)

Answers

The value is 1 dollar.
With compound interest rate of 9% over 4 period.
=> 1 dollar * .09 = 0.0081
=> 1.0081 * 0.09= 0.090729
=> 0.090729 + 1.0081 = 1.098829
=> 1.098829 * .09 = 0.09889461
=> 1.098829 *+ 0.09889461  = 1.19772361
=> 1.19772361 * .09 = 0.1077951249
=> 1.19772361 + 0.1077951249 = 1.3055187349

Answers

Answer: To find the height of a rectangle with a base of 12 cm and an area of 60 cm², we can use the formula:

Area=Base×Height

Rearranging this formula to solve for the height, we get:

Height=BaseArea​

Substituting the given values, we get:

Height=12 cm60 cm²​=5 cm

Therefore, Chloe is the only student who wrote the correct formula to find the height of the rectangle. The correct formula is:

Height=Base Area​

Cara has $25 to buy dry pet food and treats for the animal shelter. A pound of dog food cost $2 and treats are $1 apiece. If she buys 9 pounds of food, what is the greatest number of treats she can buy?

Answers

If dog food costs $2 a pound and Cara buys 9 pounds, her expenditure on dog food is 9 x 2. This makes $18. If she has a total budget of $25 and spends $18 on dog food, she has $7 left over for treats (25 - 18 = 7). At $1 each, she can buy up to 7 treats.

How many terms are in this equation
8y-6y^2/7^3

Answers

Answer:

2

Step-by-step explanation:

You count terms that are seperated by - and + signs. Any type of fraction is considered one term.

So you count 8y as one term and the rest is a whole fraction so you also count that as one term.

You add all the terms together and you have 2 terms in this equation.
