Answer:

(x+1)(x+7)

Step-by-step explanation

To find the factor of x^2+8x+7 you have to find the missing numbers m and n. Ex. (x+m)(x+n) If you evaluate this expression you will get

x^2+(m+n)x+mn. So from here you just need to find the numbers that fulfill the conditions of m and n. You can do this by just guessing and checking.

You'd have to use the Null Factor law in order to find your factors that is -7 and -1 therefore x is the element of -7 and -1.
hope this helps

What polynomial, when divided by 7y^3, yields 3y^2-4y+7 as a quotient?

weqwewe [10]

Answer: 21y^5-28y^4+49y^3

If the remainder isn't necessarily zero, we add C_1y^2+C_2y+C_3, which covers all possible remainders when dividing by a polynomial with leading term in y^3.

Step-by-step explanation:

(3y^2-4y+7)(7y^3) =

21y^5-28y^4+49y^3

The diagonals of a square measure 14cm. Which is the length of a side of the square?

Sedaia [141]

The sides of a square have the same lengths, so the diagonal and two sides form a 45-45-90 right triangle. In a 45-45-90 triangle, the hypotenuse has a length with is $\sqrt{2}$ longer than the legs.

Therefore, the sides of the square would be $\frac{14}{ \sqrt{2} }$ .

Rationalize the fraction be multiplying the numerator and denominator by root 2.

$\frac{14 \sqrt{2} }{2}$

The 14 and 2 will reduce to 7, and the answer is A.
