8 pieces.
Expression: 4 x 2
Since we are dividing in half for all of them and counting the total, you just need to double 4 or multiply by 2.
4 x 2=8.

Factor the following expression <br> 10x^5+5x^3-14x^2-7-
Tatiana [17]

Answer:

C. (5x^3-7)(2x^2+1)

Step-by-step explanation:

Given expression is,

10x^5+5x^3-14x^2-7

=10x^5-14x^2 + 5x^3 - 7  (By the commutative property)

=2x^2(5x^3-7)+5x^3-7     (Taking 2x^3 common from first two terms )

=(5x^3-7)(2x^2+1)      (Taking 5x^3-7 common from both terms)

\implies 10x^5+5x^3-14x^2-7=(5x^3-7)(2x^2+1)

Hence, Option C is correct

It's the day before Valentine's Day and Shelly needs to get Valentine cards for all of her classmates.The desks are arranged in
Vitek1552 [10]

Answer:

32

Step-by-step explanation:

No of desks along  length of the rectangle = 7 as it is 7 rows wide.

No of desks along  breadth of the rectangle = 7 as it is 5 rows long.

Total number of students is product of these two numbers.

So number of students = 35.

But three desks are empty.

Total students = 35- 3

                         = 32.

Which equation could be used to solve this problem? The sum of two consecutive odd integers is 24. Let n represent the first int
USPshnik [31]
If n is the first integer, then n+2 is the second one. The equation for the sum can be written as
  n + (n+2) = 24 . . . . . . this equation can be used to solve the problem

  2n = 22 . . . . . . . . . . . simplify, subtract 2
  n = 11

The integers are 11 and 13.

_____
I like to solve problems like this by looking at the average of the integers. Here, it is 24/2 = 12. The consecutive odd integers whose average is 12 are 11 and 13.

Xavier and Yolanda both have classes that end at noon and they agree to meet every day after class. They arrive at the coffee sh
Leto [7]

Answer:

\mathbf{ \int_{0}^{10} \int_{y}^{y+45} f(x)g(y)dxdy }

Step-by-step explanation:

Ask yourself, when will Xavier and Yolanda meet??

Firstly, since it is given that Xavier doesn't wait at all, in order for them to meet, Yolanda must arrive before Xavier. This in mathematical terms can be expressed as

Y \leq X

Secondly, Yolanda will wait for only 45 minutes, So Xavier must arrive before that, i.e

X \leq Y+45

Combining both conditions, we obtain

Y \leq X \leq Y+45

If f(x) and g(y) be the density functions for Xavier and Yolanda respectively, the probability of meeting is given by,

\int_{0}^{10} \int_{y}^{y+45} f(x)g(y)dxdy.
