Which expression is equivalent to the expression shown ? 2 (x + 5) +3 (x2 - 5x +13)

1 answer:

3 0

$\text{Use the distributive property:}\\\\a(b+c)=ab+ac$

$2(x+5)+3(x^2-5x+13)=(2)(x)+(2)(5)+(3)(x^2)-(3)(5x)+(3)(13)\\\\=2x+10+3x^2-15x+39=3x^2-13x+49$

. What are the exact solutions of x2 - x - 4 = 0?

Dimas [21]

X ² - x - 4 = 0
$x_{1} = \frac{1+ \sqrt{1+16} }{2}= \frac{1+ \sqrt{17} }{2} = 2.56$
$x_{2} = \frac{1- \sqrt{17} }{2}= - 1.56$
Exact values are x 1 = 2.56 and x 2 = -1.56

Answer:

<h3>Question 1 </h3>

<em>Adjacent angles are supplementary, opposite angles are equal</em>

62 + 5x + 3 = 180
5x = 180 - 65
5x = 115
x = 23

62 = 3y + 2
3y = 60
y = 20

<h3>Question 2</h3>

<em>Diagonals bisect each other</em>

4x = 3x + 7
x = 7

6y = 2y + 16
4y = 16
y = 4

Correct choice is A

Answer:

a. the number of people at Friday's, Saturday's, and Sunday's performances combined.

Step-by-step explanation:

The reason this information is needed to solve this problem is because we are looking to find the number of people who attended Saturday's performance. Without any information on Saturday's performance, there is no way to solve the problem. We are given the number of people on Friday and Sunday's performance, but are not given a total amount of people on all performances.
