write an expression for the perimeter of the triangle shown below 2.3x + 14 2x -0.2x + 15
Answers
Answer:
4.1x + 29
Step-by-step explanation:
So the perimeter would be the sum of all of the sides, so:
[tex]2.3x + 14 + 2x - 0.2x + 15\\= 4.1x + 29[/tex]
Answer: 4.5x+ 29 which is 3, so 3 is correct.
Step-by-step explanation:
P = a+b+c
First do the ordered pairs ( add the numbers with the x to the end, then add the other numbers with no x's)

Answers
Answer:
okay, so let's take an example problem:
y = x + 4 where "y" = 5
so first, you plug in 5 in "y"'s place like so:
5 = x + 4
then, you solve for "x"
5 - 4 = 1
so therfore:
x = 1

(3a+2.5b)^2=9a^2+6.25b^2+*
Please help before Thursday
Answers
Step-by-step explanation:
We have (x + y)² = (x + y)(x + y) = x² + 2xy + y².
Let x be 3a and y be 2.5b.
Therefore (3a + 2.5b)²
= (3a)² + 2(3a)(2.5b) + (2.5b)²
= 9a² + 15ab + 6.25b².
Hence the '*' sign should be replaced with 15ab.
Answer:
Given that, ( 3a + 2.5b )² = 9a² + 6.25b² + *
We know that, ( x + y )² = x² + y² + 2xy
According to the above problem, we get
( 3a + 2.5b )² = (3a)² + (2.5b)² + (2×3a×2.5b)
( 3a + 2.5b )² = 9a² + 6.25b² + 15ab
Therefore,
The sign " * " should be 15ab.
15ab is the right answer.What is the domain of the function y = 2e graphed below?

Answer:
Y=mx+b is an equation for a linear equation
M is the slope of the line and B is the y-intercept
The y-intercept of this line is the value of y at the point where the line crosses the y axis.
Every straight line can be represented by an equation: y = mx + b.

El perímetro de un rombo es igual al de un pentagono regular más 9, y la medida del lado del rombo es el doble de lo que mide un lado del pentagono. ¿Cuánto miden los lados de cada figura?
Answers
Answer:
Rombo es 6
Pentágono es 3
Step-by-step explanation:
Formula del perímetro de un rhombus es 4a
Formula del perímetro de un pentágono es 5b
La pregunta dice
4a = 5b + 9
Otra vez, la pregunta dice la medida del lado del rombo es el doble de lo que mide un lado del pentagono. Entonces,
a = 2b
Si
4a = 5b + 9 y
a = 2b, entonces que
4(2b) = 5b + 9
8b = 5b + 9
8b - 5b = 9
3b = 9
b = 9/3
b = 3
si, b = 3, tan
a = 2(3)
a = 6
Entonces, la medida del lado del rombo es 6 y la medida del lado del pentágono es 3

How can the decimal 1.245 repeating be written as a quotient of two integers?
Answers
Answer:
1244/999
Step-by-step explanation:
So we have 1.245245245245.... which we call x.
If we times this by 1000 (because 3 digits repeat) we get
1000x = 1245.245245245....
Subtract x from both sides:
999x = 1245.245245245... - 1.245245... = 1244
This means that x = 1244/999
This fraction cannot be simplified so this is the answer.
If you want to include the 1 in the repeating (1.2451245...) do the same but the sequence is 4 digits so times by 10000 instead.

Answer:
8 units
Step-by-step explanation:
The formula for the area of a parallelogram is base * height = area. You have that the height = 5 and the area = 40, so that means base * 5 = 40.
If base * 5 = 40, you know that base = 8. You can also solve this like an equation:
b * 5 = 40
divide both sides by 5
b = 40/5 = 8 units

Sandy has 10 roses, 2 daisies, and 8 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number of flowers and the same type of flower. What is the greatest number of flowers that could be in a bouquet?
Answers
Answer: The greatest number of flowers that could be in a bouquet = 2
Step-by-step explanation:
Given: Sandy has 10 roses, 2 daisies, and 8 tulips.
Each bouquet has the same number of flowers and the same type of flower.
The greatest number of flowers that could be in a bouquet = GCD (10,2,8)
Since 10=2 x 5, 8 = 2 x 2 x 2
GCD (10,2,8) =2
Then, The greatest number of flowers that could be in a bouquet = 2
