5 hundreds is 500. So 500x10= 5000.
Answer:5000
Answer:
B. (m-1)(m-8)
Step-by-step explanation:
The factors of 8 (constant term) are
{(1,8), (2,4)}, from which we see that 1+8 = 9, the absolute value of the coefficient of the second term.
Therefore we can group the expression as
m^2 - 9m + 8
= m^2-m - (8m -8)
then factor each group
= m(m-1) - 8(m-1)
and factor out (m-1)
= (m-1)(m-8)
-5x +2/9 +2x- 2/9 =7/9
collect like terms
-3x+0=7/9
cross-multiply
-27x=7
solve for x
x=-7/27
Answer:
(x + 7)(2x + 3)
Step-by-step explanation:
Given
2x² + 17x + 21
Consider the factors of the product of the x² term and the constant which sum to give the coefficient of the x- term.
product = 2 × 21 = 42 and sum = + 17
The factors are + 14 and + 3
Use these factors to split the x- term
2x² + 14x + 3x + 21 ( factor the first/second and third/fourth terms )
= 2x(x + 7) + 3(x + 7) ← factor out (x + 7) from each term
= (x + 7)(2x + 3) ← in factored form
When multiplying two binomials (expressions with two terms), you can use the FOIL method. Our two binomials are (3x - 7) and (3x - 5).
See picture. FOIL is an acronym for
First,
Outside
, Inside
, Last. Add the products of the first, outside, inside, and last terms of each binomial to multiply binomials.
For this problem:1) Multiply the
first terms, 3x and 3x.

2) Multiply the
outside terms:

3) Multiply the
inside terms:

4) Multiply the
last terms:

5) Add all the products from FOILing together:
