Use the Distributive Property to write each expression as an equivalent algebraic expression. (7 + a)3 Question 4 options: 3(7a) 21 + 3a 10 + 3a 7 + 3a
Answer:
(B)21+3a
Step-by-step explanation:
An expression is said to be distributive when:
[tex](a+b)c=a \cdot c+b \cdot c[/tex]
Given the algebraic expression: (7 + a)3
Applying the distributive property
[tex](7 + a)3 = 7 \cdot 3+a \cdot 3\\=21+3a[/tex]
An equivalent expression is 21+3a.
The correct option is B
Try to answer the following question without running the code in Python:
If we run the following program:
a = 2 + 6
b = 7 % 3
c = a - b
c = c * 5
print(c)
what gets printed?
Answer:
35
Step-by-step explanation:
Given
the above lines of code
Required
What's the output
We'll analyze the code line by line
a = 2 + 6
At this point a = 8
b = 7 % 3
At this point b = 1. This is so because, the remainder of 7%3 is 1
c = a - b
At this point c = 7;
This is calculated by c = 8 - 1 = 7
c = c * 5
At this point; c = 35
This is calculated by: c = 7 * 5 = 35
print(c)
The value of c, which is 35 is printed

Which group of numbers is ordered from least to greatest?
A. 45,−0.9,−3
B. −3,−0.9,45
C. −0.9,45,−3
D. 45,−3,−0.9
Answer:
The answer is option B.
-3 , - 0.9 , 45
Hope this helps you
Explanation:
The negative numbers are always smaller than the positive ones. So we list those first. The number -3 is smaller than -0.9 since it is further to left on the number line. So far we have -3 followed by -0.9. The last value must be 45 as its the only thing left. The sequence from smallest to largest is therefore -3, -0.9, 45. A number line is recommended to see the values being placed from left to right.
y=-4x-5 y=3x-2 is (3,7) a solution of the system?
Answer:
No
Step-by-step explanation:
Does (3, 7) satisfy the first equation, y = -4x - 5? Is 7 = -4(3) - 5 true? NO. Thus, (3, 7) cannot be a solution of the system
y=-4x-5
y=3x-2
The given point (3, 7) is not the solution in the given case.
What is a system of linear equations?A system of linear equations can be defined as a number of equations needed to solve the equations. For n number of variables n number of equations are required.
Given equations are as follows,
y = -4x - 5 (1)
y = 3x - 2 (2)
In order to find whether (3,7) is the solution for them, substitute x = 3 and y = 7 in both the equations and check the LHS and RHS of both.
For equation (1),
y = -4x - 5
LHS is y = 7
RHS = -4x - 5
= -4 × 3 - 5
= -17
Since, LHS ≠ RHS, the given values of x and y are not the solution for the given equation.
Now, equation(2) need not to be checked as the result for the given values is already not valid for equation(1).
Hence, the given coordinate (3,7) is not the solution for the given equations.

What is the domain of the function y= Vx+4
Answer:
y = √ x + 4
The domain of a function is the value in which you put in the function will make it undefined.
To find the domain equate the function to zero
That's
√x + 4 = 0
square both sides
x + 4 = 0
x = - 4
The domain of the function is x E R except - 4
Hope this helps

Answer:
70 degrees
Step-by-step explanation:
All angles in a triangle add up to 180 degrees.
x + 65 + 45 = 180
x + 110 = 180
x = 180 - 110
x = 70
The size of angle x is 70 degrees.
Answer:
70
Step-by-step explanation:
180-65-45=70

two angles of a triangle measure 27 degrees and 17 degrees what is the measure of the third angle? A) 146 degrees B) 136 degrees C) 46 degrees D) 44 degrees
Answer:
The third angle is 136
Step-by-step explanation:
The three angles of a triangle add to 180
27+17+x = 170
Combine like terms
44+x = 180
Subtract 44 from each side
44+x-44 =180-44
x =136
Answer:
136° is the answer.
Step-by-step explanation:
given ,
1st angle=27°
2nd angle= 17°
let the third angle be x
then ,x+27°+17°=180°
or x+44°=180°
or, x=180_44
therefore the value of x is 136°.

x+x-47=x+42
x=42+47
x=89°
Hey there! :)
Answer:
x = 89°.
Step-by-step explanation:
x + 42 is supplementary to the inside angle at the top of the triangle, so:
The top angle of the triangle is equal to:
180 - x - 42.
All of the angles in a triangle add up to 180°, therefore:
180 = x + x - 47 + 180 - x - 42
Combine like terms:
180 = 2x + 133 - x - 42
180 = x + 91
Subtract 91 from both sides:
89 = x.
Therefore, x = 89°.

On a map, 1 cm represents 3 km. The real-life distance between two towns is 27 km. What is the distance between these two towns on a map?
Answer:
9 cm
Step-by-step explanation:
Every centemeter represents three. 3km=1cm.
The number of kilometers/3= the number of centemeters.
the number of centemeters x 3= the number of kilometers.
We now have three equations to help us covert back and forth.
The question asks us to convert 27km in real life, to centemeters on a map. We use the first forumla to help us:)
The number of kilometers/3= the number of centemeters.
27/3=the number of centemeters.
Thus, the answer is nine.
Answer:
9cm
Step-by-step explanation:
1:3 this is the starting ratio
if we replace 3 for 27 we just divide them to get 9 so the new ratio is 9:27.
