PLEEEAAAAAASE HELP!<br>What is the answer to this question?<br><br>​
IrinaVladis [17]

Answer:

  • 23 units

Step-by-step explanation:

<em>Perimeter is the sum of side lengths</em>

<u>Let's find the sides first</u>

  • AB = √(-2- 2)² + (-4+1)² = 5
  • BC = (2 - (-1)) = 3
  • CD = √(-1- 2)²+(5-2)² = √18 = 3√2 = 4.24
  • DE = √(-4 -(-1))²+(2-5)²= √18 = 3√2 = 4.24
  • AE = √(-4-(-2)²+(2-(-4))²=√40= 2√10 = 6.32

<u>Perimeter is</u>

  • P = 5 + 3 + 4.24 + 4.24 + 6.32 = 22.8 ≈ 23 rounded to the nearest whole number

Given 14 – 2(x + 8) = 5x – (3x – 34), prove x = -9 what are the steps to be able to prove x=-9
Veronika [31]

Answer: x = -9

steps

Simplifying

14 + -2(x + 8) = 5x + -1(3x + -34)

Reorder the terms:

14 + -2(8 + x) = 5x + -1(3x + -34)

14 + (8 * -2 + x * -2) = 5x + -1(3x + -34)

14 + (-16 + -2x) = 5x + -1(3x + -34)

Combine like terms: 14 + -16 = -2

-2 + -2x = 5x + -1(3x + -34)

Reorder the terms:

-2 + -2x = 5x + -1(-34 + 3x)

-2 + -2x = 5x + (-34 * -1 + 3x * -1)

-2 + -2x = 5x + (34 + -3x)

Reorder the terms:

-2 + -2x = 34 + 5x + -3x

Combine like terms: 5x + -3x = 2x

-2 + -2x = 34 + 2x

Solving

-2 + -2x = 34 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

-2 + -2x + -2x = 34 + 2x + -2x

Combine like terms: -2x + -2x = -4x

-2 + -4x = 34 + 2x + -2x

Combine like terms: 2x + -2x = 0

-2 + -4x = 34 + 0

-2 + -4x = 34

Add '2' to each side of the equation.

-2 + 2 + -4x = 34 + 2

Combine like terms: -2 + 2 = 0

0 + -4x = 34 + 2

-4x = 34 + 2

Combine like terms: 34 + 2 = 36

-4x = 36

Divide each side by '-4'.

x = -9

HELP <br><br> Find the Axis of Symmetry
balu736 [363]

Answer:

Axis of symmetry= 3

Step-by-step explanation:

f(x)= 2x^2 +12x-4

f(x)=ax^2+bx+c

x=12/2(2)

x=3

f(x)= 2(3)^2+12(3)-14

f(x)= 2(9)+36-14

f(x)=18+36-14

f(x)= 54-14

y=40

Delia is bagging 24 onion bagels and 16 plain bagels for her bakery customers. Each bag will hold only 1 type of bagel. Each bag
Mnenie [13.5K]
<h2>Answer:</h2><h2>8 bagels in each bag, 3 bags of onion, 2 bags of plain</h2>

24 onion bagel

16 normal bagel

We need the GCF (Greatest Common Factor) of 16 and 24 to find the answer.

Factors of 16 = 1, 2, 4, 8, 16

Factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24

What is the GCF? It is 8.

Hence, 8 bagels in each bag.

24/8 = 3 bags of onion bagels

and

16/8 = 2 bags of plain bagels
