Find the Greatest Common Factor (GCF)

GCF = 5

Factor out the GCF (Write the GCF first, then in parenthesis, divide each term by the GCF)

5(5x^2/5 + 40x/5 - 100/5)

Simplify each term in parenthesis

5(x^2 + 8x - 20)

Factor x^2 + 8x - 20

<u>= 5(x - 2)(x + 10)</u>

Answer:

5(x+10)(x-2)

Step-by-step explanation:

To solve this problem, take 5 as a common factor of expression

5(x^2 +8x - 20)\\

Now look for two numbers that multiplied are equal to -20 and when you add both you get 8.

These numbers are 10 and -2.

Then we write the expression as:

5(x+10)(x-2)

Sam has fewer baseball cards than Jill (she has 36). There are only three ways that he can arrange all of his cards in equal row
pantera1 [17]

Answer:

27, 30, 33

Step-by-step explanation:

Since Sam has fewer number of baseball cards than Jill who has 36 baseball cards and can arrange all his cards in only three ways, the possible number of baseball cards that Sam could have is 27, 30 or 33.

If he has 27 baseball cards, he can arrange 9 baseball cards per row in 3 rows

If he has 30 baseball cards, he can arrange 10 baseball cards per row in 3 rows

If he has 33 baseball cards, he can arrange 11 baseball cards per row in 3 rows

One solution to a quadratic function, h, is given.
Margaret [11]

Answer:

B. The other solution to function h is -4-i\,7.

Step-by-step explanation:

From Algebra, we remember that quadratic functions of the form a\cdot x^{2}+b\cdot x + c has solutions of the form:

x = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}, where both are complex if and only if \sqrt{b^{2}-4\cdot a \cdot c}< 0.

Hence, if one solution of the quadratic function is -4+i\,7, then the other solution is -4-i\,7. The correct answer is B.
