Answer:
You can use estimation to check for reasonableness when you have math problems with all numbers. When you do use estimation, it won't tell you whether you actually have the correct answer, but it will tell you if you're close and your answer is probably right.

Hey There!
In order for two equations to be parallel they have to have the same slope
The only answer with equation that have the same slope is b
They both have a slope of 2
Hope this helps :)
Answer:
B.
Step-by-step explanation:
If two lines are parallel, that means that their slopes are the same.
If they're perpendicular, their slopes would be the negative reciprocal of the other.
For example, if line 1's slope was 5 and line 2 was parallel to it, that means that line 2's slope must be 5 as well. If line 3 was perpendicular to line 1, that meant that line 3's slope would be -1/5.
In triangle ABC, the measure of angle CAB is 80° and the measure of angle ABC is 45.5°.
What is the measure of angle BCA in degrees?
A 125.5°
B 54.5°
C 55.5°
D 64.5°
Answer: B
Because triangles add up to 180 degrees, all you need to do is subtract 45.5 and 80 from 180, which gives you 54.5 degrees.
Hope this helped you!
please help will mark right answer brianlyist
Answer:
b = 64°
2b = 128°
Step-by-step explanation:
use (n-2)×180 to find the total number of degrees inside a polygon where 'n' equals number of sides
hexagon has 6 sides; (6-2)×180 = 720°
528 + 3b = 720
3b = 192
b = 64

A rectangle has a length of 4 meters. The width is 2 meters more than the length. Work out the area.
Answer:
24 m^2
Step-by-step explanation:
Given data
Length= 4 meters
Width= 2+4= 6 meters
We know that the expression for the area of a rectangle is given as
A= Lenght* Width
A= 4*6
A= 24m^2
Hence the area is 24 m^2

Answer:
8 but more than 6
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
The triangle side rule is that the two smaller side have to be added together and be greater than the longest side
6+8=14
so any number that is 14 or more cannot be the other side
Therefore the third side must be less than 14 inches

I’m confused on how to find the equation...(help ASAP) thxxxxx
Answer:
Step-by-step explanation:
Remark
You can use the two points marked to find the slope. One of them is the y intercept which you need to get the equation.
(0,4) is one of the points. This is the y intercept.
(8,0) is the other point you can use
Slope
m = (y2 - y1)/(x2 - x1)
Givens
y2 = 4
y1 = 0
x2 = 0
x1 = 8
Solution
m = (4 - 0) / (0 - 8)
m = 4/-8
m = - 1/2
y_intercept = 4
Equation
y = -1/2 x + 4

Which of the following statements are true? Select all that apply.
(Y=136)
Answer:
B. x + y = 180° and C. y = z
x = 180° - 82° - 54°
x = 64°
x + y = 180°
64° + 136° = 180°
so, x + y = 180° it's should be correct
∠y°,∠z° are vertical opposite angles.

3.The side of a square frame is (2b - 1) inches. Find its area.
Note: Area of a square
s2, where s = side of a square
Answer:
Step-by-step explanation:
(a - b)² = a² + 2ab + b²
Area of square frame =side²
= (2b - 1)²
= (2b)² - 2*2b * 1 + 1²
= 4b² - 4b + 1
