Answer:
2(m + [n)] + [1]
Step-by-step explanation:
(2m) + (2n + 1) =
= 2m + 2n + 1
= 2(m + n) + 1
= 2(m + [n)] + [1]
The simplification of the expression would be equal to 2(m + [n)] + [1].
What is a simplification of an expression?Usually, simplification involves proceeding with the pending operations in the expression.
Like, 5 + 2 is an expression whose simplified form can be obtained by doing the pending addition, which results in 7 as its simplified form.
Simplification usually involves making the expression simple and easy to use later.
An even plus an odd equals an odd.
[tex](2m) + (2n + 1)\\= 2m + 2n + 1\\= 2(m + n) + 1\\= 2(m + [n)] + [1][/tex]

Answer:
AB = 10 m
Step-by-step explanation:
Given that <ACB = <ECD, then triangles ABC and EDC are similar.
Let the height of the solar panel (AB) be represented by x. Thus by comparing the triangles, we have;
[tex]\frac{x}{6}[/tex] = [tex]\frac{45}{75}[/tex]
45x = 6 x 75
45x = 450
x = [tex]\frac{450}{45}[/tex]
x = 10
The height of the solar panel is determined to be 10 m.

Zach has an above-ground pool that has a radius of 5.5 feet. He wants to put a new wall liner around his pool and needs to know the circumference of the pool. Find the circumference of the pool to the nearest hundredth.
Answer: 34.54feet
Step-by-step explanation:
Thw circumference of the pool will be calculated by using the formula:
= 2πr
where
π = 3.14
r = 5.5
Therefore, circumference = 2πr
= 2 × 3.14 × 5.5
= 34.54feet
Therefore, the circumference of the pool to the nearest hundredth is 34.54feet.

Step-by-step explanation:
Sami was asked to solve the following system of equations using substitution.
y=6x -4
y=2x
Here is the work that sami did:
2x = 6x -4
8x = -4
x = -0.5
And then to find y: y= 2 (-0.5) = -1
so Sami's answer for the point of intersection was (-0.5, -1).
Clearly state Sami's one error and then give the correct ordered pair for where the lines cross.
Answer:
see explanation
Step-by-step explanation:
Sami's error is in the second line of working
2x = 6x - 4 ← correct substitution ( subtract 6x from both sides, Sami has added 6x )
- 4x = - 4 ← correct second line ( divide both sides by - 4 )
x = 1
Substitute x = 1 into either of the 2 equations and evaluate for y
Substituting into the second equation
y = 2x = 2(1) = 2
solution is (1, 2 )
4. Two consecutive even numbers are such that the sum of the larger number and three times the smaller number is 42. Find the two numbers.
Answer: The two numbers are 10 and 12.
Step-by-step explanation:
Let the two consecutive numbers are x and x +2.
As per given, we have
[tex](x+2)+3x=42\\\\\Rightarrow\ 4x+2=42\\\\\Rightarrow\ 4x=40\\\\\Rightarrow\ x=10[/tex]
Smaller number = 10
Larger number = 10+2=12
Therefore, The two numbers are 10 and 12.

What is the y-intercept?
Write the equation of the line?
Answer:
The slope is 2
The y-intercept is 3
The equation is y = 2x +3
Step-by-step explanation:
The equation goes up 2 squares and over 1 square. 2/1 = 2
For y-intercept, look at the y-axis
The equation is supposed to be written as y = mx + b
m being the slope and b being the y-intercept.

Determine the area of the parallelogram.use proper units
Answer:
180 in^2
Step-by-step explanation:
to find the height you need to look at the triangle and apply pythagorean theorem
5^2=x^2=13^2
25+x^2=169
x^2=144
x=12
now we can find the area of the parallelogram:
b*h=area
15*12=180 in^2
The area of the parallelogram is 180 in^2

Answer:
1A. acute. all of the angles are under 90%. acute is under 90%, right is 90%, and obtuse is over 90%
2A. scalene. isosceles is all sides are the same length, and equilateral is all sides are the same length AND all the angles are 60%. with scalene all sides can be different lengths, and angles can be different
3. no. the rule for making a triangle is that any 2 sides added up, must be more than the 3rd side. so 6+2, 6+4 work, but 2+4 is 6, which is not greater than 6, the third side
