Perfect square trinomial means that the constant term is a perfect square, and the middle term is the sum of it's factors.
Option 1: constant 64 sqrt = 8; 8 + 8 = 16 or -8 + -8 = -16 NO
Option 2: constant 36 sqrt = 6; 6 + 6 = 12 or -6 + -6 = -12 NO
Option 3: constant 64 sqrt = 8; 8 + 8 = 16 or -8 + -8 = -16 YES
(x - 8)^2 is the factored form

$\sqrt{2} \times \sqrt{800}$

$\sqrt{2} \times 20 \sqrt{2}$

$\sqrt{2} \times \sqrt{2} = \sqrt{4} \: = 2$

$20 \times 2 = 40$

$therefore \: \: \: \sqrt{2} \times \sqrt{800} = 40$

Please help me fast I still nee to finish 2 more ixl's by monday!!!!

Answer:No

Step-by-step explanation:

Given system of equation is:

2x + 3 = y

2x + y = 15

To check whether (2,7) is solution to this system or not, we will put x=2 and y=7 in both equations.

Putting x=2 and y=7 in Eqn 1

2(2) + 3 = 7

4 + 3 = 7

7 = 7

Thus the ordered pair satisfies the equation

Putting x=2 and y=7 in Eqn 2

2(2) + 7 = 15

4 + 7 = 15

11 ≠ 15

The ordered pair do not satisfy the second equation.

Hence,

(2,7) is not a solution to the given system of equations.

Factor the polynomial. 7x2 + 68xy - 20y2 A) (7x - 2y)(x + 10y) B) (7x - 10y)(x - 2y) C) (7x + 10y)(x + 2y) D) (7x + 2y)(x - 10y)

Otrada [13]

For this case we have the following polynomial:
7x2 + 68xy - 20y2
Factoring we have:
(7x-2y) (x + 10y)
We verify the factorization:
7x2 + 70xy - 2xy - 20y2
Rewriting we have:
7x2 + 68xy - 20y2
Therefore, the factorization is correct.
Answer:
A) (7x - 2y) (x + 10y)

Pls Help: I need help

Answer: C

Step-by-step explanation: 0.571 is greater than 0.4. Therefore, 4/7 is greater than 2/5 and the answer to the question "Is 4/7 greater than 2/5?" is yes. Note: When comparing fractions such as 4/7 and 2/5, you could also convert the fractions (if necessary) so they have the same denominator and then compare which numerator is larger.
