Answer:

Option: a is the correct answer.

a. if your answer is reasonable, you have probably done the problem correctly.

Step-by-step explanation:

Checking for reasonableness is a process by which students evaluate estimations to see if they are reasonable guesses for a problem.

So, a good idea to check to see if your answer is reasonable is:

a. if your answer is reasonable, you have probably done the problem correctly.

( Since a reasonable answer is just a estimation of the problem it can't be claimed to be true but it is just a probable estimation ).

Answer:

OXY=18

Step-by-step explanation:

The ratio of AABC to AAXY is 4:3 so the lengths will be in that ratio too. The ratio of BC:XY is 4:3. BC is 24 so 24:XY is 4:3. You need to divide 24 by 6 to get 4 so multiply 3 by 6 to get the answer 18.

Prove the polynomial identity.

Kaylis [27]

Answer:

Proven

Step-by-step explanation:

We prove the polynomial with factorization. We must first simplify the expression before we can factorize:

$(4\cdot{x^2}-2)\cdot{(4\cdot{x^2}-2)}-16\cdot{x^4}$

$16\cdot{x^4}-8\cdot{x^2}-8\cdot{x^2}+4-16\cdot{x^4}$

$4-16\cdot{x^2}$

4 is the common number and we can take it out of the expression:

$4\cdot{(1-4\cdot{x^2})}$

We can factorize further with the x term being zero. For this to be true we must have -2x and 2x to cancel out and therefore the expression is proven:

$4\cdot{(1-2\cdot{x})}\cdot{(1+2\cdot{x})}$

Seven times a number decreased by three-fourths of the same number is 25. What is the number?

Tomtit [17]

Answer:

103/28

Step-by-step explanation:

Let the number be 'x'

Equation:-

7x - 3/4 = 25

7x = 25 + 3/4

7x = 100/4 + 3/4

7x = 103/4

x = 103/(4 x 7)

x = 103/28
