A student attempted to generate an equivalent expression using the distributive property, as shown below:
3(p − 4) = 3p − 4
What was the mistake made? (1 point)
a
3 was not multiplied by p
b
3 was not multiplied by −4
c
Incorrect sign was used for the first term
d
Incorrect sign was used for the second term
20 POINTS HELP ASAP
Answer:
b 3 was not multiplied by −4
Step-by-step explanation:
The correct way to apply the distributive property is to multiply 3 by p and multiply 3 by -4 as shown below.
3(p − 4) = 3p + 3 × (-4) = 3p - 12
His attempt is
3(p - 4) = 3p - 4
He did multiply 3 by p, but h did not multiply 3 by -4.
Answer: b 3 was not multiplied by −4
Segment AB falls on line 6x + 3y = 12. Segment CD falls on line 4x + 2y = 8. What is true about segments AB and CD?
They are parallel because they have the same slope of -2.
1
They are parallel because they have the same slope of
2
They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.
They are lines that lie exactly on top of one another because they have the same slope and a different y-intercept.
Answer: C
Step-by-step explanation:
The slope-intercept form of a line is given by
y = mx + b
m - slope
b - y-intercept
Segment AB lies on the line 6x + 3y = 12
6x + 3y = 12
3y = -6x + 12
y = -6/3x + 12/3
y = -2x + 4
Comparing with the slope-intercept form,
Slope = - 2
y-intercept = 4
Segment CD lies on the line 4x + 2y = 8
4x + 2y = 8
2y = -4x + 8
y = -4/2x + 8/2
y = - 2x + 4
Comparing with the slope-intercept form,
Slope = - 2
y-intercept = 4
Both the line segments have the same slope and the same y-intercept, so the two line segments will lie exactly on top of one another.
Therefore, the correct option is (c)

A right triangular prism is sliced perpendicular to its base. What is the shape of the resulting two-dimensional cross section?
trapezoid
rhombus
rectangle
square
Answer:
answer is C. Rectangle
Step-by-step explanation:
The shape of the resulting two-dimensional cross section is a rectangle.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
A right triangular prism has a base that is a right triangle, and the prism has three perpendicular rectangular faces that join the two congruent triangles.
When this prism is sliced perpendicular to its base, the resulting two-dimensional cross-section will always be a rectangle.
This is because the cut will be perpendicular to the rectangular faces of the prism and the base triangle, resulting in a rectangle.
The length of the rectangle will be equal to the base of the triangle, and the width of the rectangle will be equal to the height of the prism.
Hence, shape of the resulting two-dimensional cross section is a rectangle.

When you're drawing an inequality on a number line there are a few things to focus on:
- Whether your variable is greater than or less than the number
- Whether it can be equal to the number or not
If it can be equal to the number your first dot will be filled in, if not it will be hollow
When it's less than it means you're moving to the left on your number line, if it's greater than you move right

Austin is building a miniatuer replica of the empire state building.The actual empire state building is 1,423 feet tall and 6,000 feet wide .If astin's replica has a width of 60 centimeters, what is the height of his empire state building replica rounded to the nearest centimeter?
Answer: 14cm
Step-by-step explanation:
From the question, we are informed that Austin is building a miniatuer replica of the empire state building and that the actual empire state building is 1,423 feet tall and 6,000 feet wide
We are further told that Austin's replica has a width of 60 centimeters. This implies that the scale of 1:100 was used where 1cm represents 100 feet
= 60:6000
= 1:100
Therefore, the height of his empire state building replica rounded to the nearest centimeter will be:
= 1423/100
= 14.23cm
= 14cm approximately
