simplify the expression a² • 3a and explain your steps pls
Answer:
3a^3
Step-by-step explanation:
Ok I got you bud now the the first thing to notice that they're all the same variable. so the way I learned to look at is like this
1a^2 x 3a^1
so the reason I put it like this is so I remember that in front of every variable is a coefficient. so you would first multiply the coefficient
3x1=3
3
then multiply the a's you have one a that is being squared and one a to the first power so since your multiplying them you just add the exponents
a^1 + a^2 = a^3
so when you put it all together it says 3a^3

Answer:
DE is parallel to AC
DE = 2AC
ExplanationIn triangle ABC, BD = AD
BE = EC
D is mid point of AB
E is the mid point of AC
According to the mid point theorem, ( The line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.”) DE is parallel to AC and equal to half of it
Answer:
For clarification, the answer is DE||AC or in other words, DE is parallel to AC.

Answer: Good luck guys
a) 4(9 x - 18) > 3(8x + 12)
The solution to the inequality is x > 9.
Graph A.
b) -1/3 (12x + 6) ≥ -2x + 14
The solution to the inequality is x ≥ -8.
Graph B.
c) 1.6 (x + 8) ≥ 36.4
The solution to the inequality is x ≥ 14.75.
Graph C.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
a)
4(9x - 18) > 3(8x + 12)
First, we can simplify both sides of the inequality:
36x - 72 > 24x + 36
Next, we can isolate the variable on one side by subtracting 24x from both sides:
12x - 72 > 36
Finally, we can isolate x by adding 72 to both sides:
12x > 108
x > 9
Therefore, the solution to the inequality is x > 9.
b)
-1/3(12x + 6) ≥ -2x + 14
First, we can simplify the left-hand side of the inequality:
-4x - 2 ≥ -2x + 14
Next, we can isolate the variable on one side by adding 4x to both sides:
-2 ≥ 2x + 14
Then, we can isolate x by subtracting 14 from both sides:
-16 ≥ 2x
Finally, we can divide both sides by 2, remembering to reverse the direction of the inequality because we are dividing by a negative number:
-8 ≤ x
Therefore, the solution to the inequality is x ≥ -8.
c)
1.6(x + 8) ≥ 36.4
First, we can simplify the left-hand side of the inequality:
1.6x + 12.8 ≥ 36.4
Next, we can isolate the variable on one side by subtracting 12.8 from both sides:
1.6x ≥ 23.6
Finally, we can divide both sides by 1.6:
x ≥ 14.75
Therefore, the solution to the inequality is x ≥ 14.75.
Thus,
a) 4(9 x - 18) > 3(8x + 12)
The solution to the inequality is x > 9.
Graph A.
b) -1/3 (12x + 6) ≥ -2x + 14
The solution to the inequality is x ≥ -8.
Graph B.
c) 1.6 (x + 8) ≥ 36.4
The solution to the inequality is x ≥ 14.75.

An Eurasian lynx travled 46 miles. It took the
cat 43 days. to cover this distance How many miles per
day did it travel.
Answer:
A Eurasian lynx covered 1.07 miles per day.
Step-by-step explanation:
The distance traveled by a Eurasian lynx = 46 miles
The days to cover the 46 miles distance = 43 days
Divide the total distance miles by the total number of days to determine the miles per day.
Thus,
Miles per day = Tota distance / Totdal days
= 46 / 43
= 1.07 miles per day
Thus, An Eurasian lynx covered 1.07 miles per day.

What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Maurice has a pet hamster. In October he burned through $13.68 on hamster food $7.89 on wood shavings and $21.14 on another hamster wheel.
Then the amount of money that he spent on his hamster will be given by the summation of $13.68, $7.89, and $21.14.
⇒ $13.68 + $7.89 + $21.14
⇒ $42.71
⇒ $43
The amount of money that he spent on his hamster round to the nearest dollar will be $43.

9514 1404 393
Answer:
38.5°
Step-by-step explanation:
A triangle solver can give an answer easily. The angle is 38.5°.
__
The law of cosines can be written to solve for an unknown angle C opposite side 'c' and flanked by sides 'a' and 'b'.
C = arccos((a² +b² -c²)/(2ab))
Here, we have a=35, b=48, c=30, so the angle is ...
C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360) ≈ 38.515°
The angle the cable makes with the pole is about 38.5°.

Is 3/6 divided by 5 greater than 1?
It is not greater than one.
When you divide 3/6 by 5, your quotient is 0.1, which has a value that is less than 1.
Hope this helps!
- sahira :>
Step-by-step explanation:
3/6 divided by 5
The numbers in 3/6 divided by 5 are labeled below:
3 = numerator
6 = denominator
5 = whole number
To make it a fraction form answer, you keep the numerator and multiply the denominator by the whole number to make a new denominator:
3/6 times 5 = 3/30
Thus, the answer to 3/6 divided by 5 in fraction form is:
3/30
to make the answer to 3/6 divided by 5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
3/30 = 0.1
The answer is rounded to the nearest four decimal points if necessary.
3/30 can be simplified to 1/10

Answer:
The answer is below
Step-by-step explanation:
Hana has some blue paint. She wants to lighten the shade, so she mixes in 1 cup of white paint. The color is still too dark, so Hana keeps mixing in 1 cup of white paint at a time. After adding 4 cups, she decides the color is too light.
How would she express the amount of paint to add to be between too dark and too light.
Solution:
After adding a cup of white paint, the color is still dark, she adds the second cup of paint and the color is still dark. She adds the third cup of paint and the color is still dark but when she adds the fourth cup of white paint, the color became too light.
This means that the amount of paint to add to be between too dark and too light is between the third and fourth cup.
Let w represent the amount of paint to add to be between too dark and too light. Hence:

Answer:
the y-intercept is 8 and the slope is -4/3 .
Step-by-step explanation:
The y - intercept is (0, 8) and the slope is -4/3
What is the y-intercept?"It is the point at which the graph of the function intersects the y-axis"
What is slope?The slope of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
For given example,
We can observe that the line of best fit on this scatter plot passes though points (0, 8) and (6, 0)
Using the slope formula,
⇒ slope = (0 - 8)/(6 - 0)
⇒ slope = (-8)/6
⇒ slope = -4/3
Also, we can observe that the line of best fit on this scatter plot intersects y-axis at point (0, 8)
So, the y - intercept is (0, 8)
Therefore, the y - intercept is (0, 8) and the slope is -4/3
