Use the associative property to create equivalent expressions to a + b + (c + d). Which statements are true? Check all that apply. The associative property allows us to change the grouping of terms that are added together. When changing the grouping, the order of the terms stays the same; only the parentheses change position. The expression a + (b + c) + d is an equivalent expression. The expression ab(cd) is an equivalent expression. The expression (a+ b) + c + d is an equivalent expression. The expression a + b(c + d) is an equivalent expression.
Answer:
a.The associative property allows us to change the grouping of terms that are added together.
b.When changing the grouping, the order of the terms stays the same; only the parentheses change position.
c.The expression a + (b + c) + d is an equivalent expression.
e.The expression (a+ b) + c + d is an equivalent expression.
Step-by-step explanation:
The correct statements are statement first, statement second, statement third, and statement fifth are correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
As we know,
The associative property allows us to change the grouping of terms that are added together.
= a + (b + c)
= (a + b) + c
The correct statements are:

Step-by-step explanation:
3x - 6x + 2 > 65
Mathematic
3x - 6x + 2 > 65
Combine like terms.
-3x + 2 > 65
Subtract 2 from both sides.
-3x > 62
Divide both sides by -3
x < -62/3
Answer:
3x - 6x + 2 > 62
→ -3x + 2 > 62
→ -3x > 62
→ x < -62/3
What is the standard form polynomial representing the volume of this shipping container?
6x + 15
4x² + 3x
x² – 8
Answer:
Step-by-step explanation:
Volume of the shipping container = Lengt * Breadth * Height
Given
Length = 4x² + 3x
Breadth = x² – 8
Height = 6x +15
Volume of the container = ( 4x² + 3x)( x² - 8)(6x+15)
( 4x² + 3x)( x² - 8) = 4x⁴-32x²+3x³-24x
( 4x² + 3x)( x² - 8) = 4x⁴+3x³-32x²-24x
(4x⁴+3x³-32x²-24x)(6x+15) = 24x⁵+60x⁴+18x⁴+45x³-192x³-480x²-144x²-360x
Collect like terms
( 4x² + 3x)( x² - 8)(6x+15) = 24x⁵+78x⁴-147x³-624x²-360x
Hence the standard form polynomial representing the volume of this shipping container is expressed as V = 24x⁵+78x⁴-147x³-624x²-360x
Answer:
V = 24x^5+78x^4-147x^3-624x^2-360x

Answer: I HOPE IT HELPS OR WATCH VIDOES ABOUT IT
Step-by-step explanation:
Two unique points define a line. Other geometric figures also may pass through those two points (you will learn those later).
There are several forms of the equation of a line:
Standard form Ax + By = C
Slope-intercept form y = mx + b
Point-slope form y – y1 = m(x – x1)
Two-point form y – y1 = [ (y2 – y1)/(x2 – x1) ](x – x1)
O.K., you picked the two-point form, right?
The points are P1: (5,5) and P2: (7,-4)
y - 5 = [ ((-4) - 5)/(7 - 5) ] (x - 5) (put in x and y values of points)
y - 5 = [ -9 / 2 ](x - 5) (simplify)
y - 5 = -9/2x + 45/2 (distribute -9/2)
y = f(x) = -9/2x + 55/2 (add 5 to both sided)
Check (very important):
Is (5,5) on the line? 5 = (-9/2)(5) + 55/2 ?
5 = -45/2 + 55/2 ?
5 = 10/2 yes.
Is (7,-4) on the line? -4 = (-9/2)(7) + 55/2 ?
-4 = -63/2 + 55/2 ?
-4 = -8/2 ? yes.
I need help!!!!!!!! 2c-2.6=1.8
Answer:
thats right
Step-by-step explanation:
Answer:
c= 2.2
Step-by-step explanation:
assuming your solving for c
2c-2.6=1.8 first isolate c by adding 2.6 on both sides
2c= 4.4 now divide both sides by 2
c= 2.2

Answer:
Frequency
Step-by-step explanation:
"A dot plot is a visual display in which each piece of data is represented by a dot above a number line, showing the frequency of each data value. The total number of dots in the plot is the total number of values in the data set. The data points must all be in the same units."
Solve for x: 3x−2=8x+8
Answer:
-2 =x
Step-by-step explanation:
3x−2=8x+8
Subtract 3x from each side
3x-3x−2=8x-3x+8
-2 = 5x+8
Subtract 8 from each side
-2-8 = 5x+8-8
-10 = 5x
Divide each side by 5
-10/5 = 5x/5
-2 =x
Answer:
-2
Step-by-step explanation:
Subtract 8x from both sides.
3x−2−8x=8x+8−8x
−5x−2=8
Step 2: Add 2 to both sides.
−5x−2+2=8+2
−5x=10
Step 3: Divide both sides by -5.
−5x
−5
=

Lionel computed the average rate of change in the depth of a pool over a two-week interval to be zero. Which statement must be true? The pool must have been empty for the entire interval. The pool must have been the same depth at the start of the interval as it was at the end of the interval. The pool must have been deeper at the end of the interval than it was at the start of the interval. The pool must have been more shallow at the end of the interval than it was at the start of the interv
Answer:The pool must have been the same depth at the start of the interval as it was at the end of the interval.
Step-by-step explanation:
The average rate of change is calculated as:
[final value - initial value] / time interval.
Then, the average rate of change does not take into account intermediates values, and you cannot draw any conclusion about such intermediate values.
In the given case you have:
average rate of change in depth = [final depth - initial depth] / 2 weeks.
0 = [final depth - initial depth] / 2 weeks.
⇒ 0 = final depth - initial depth
⇒ final depth = initial depth.
That is why the conclusion is the second statement of the answer choices: the pool must have been the same depth at the start of the interval as it was at the end of the interval.
In between the pool might have been deeper, more shallow, empty or change in any form, since the average rate of change does not tell the full history but only the net change.
Answer:
The pool must have been the same depth at the start of the interval as it was at the end of the interval.
Step-by-step explanation:
got it right on edge.
