Answer:
[tex]\boxed{\sf{-6n^2-3n}}[/tex]Step-by-step explanation:
This product can be solved by multiplying these parentheses left to right using a distributive property.
Distributive property:
[tex]\Longrightarrow:\sf{A(B+C)=AB+AC}[/tex]
[tex]\Longrightarrow: \sf{-n(6n+3)=-n*6n-n*3}[/tex]
Rewrite the problem down.
-n*6n-n*3
Solve.
-n*6n-n*3=-6n²-3n
[tex]\Longrightarrow:\boxed{\sf{-6n^2-3n}}[/tex]
Therefore, the correct answer is -6n²-3n.I hope this helps you! Let me know if my answer is wrong or not.

A school increases its intake by 10%. if it starts with 1000 students, how many will it have at the beginning of the fourth year of expansion?
Answer:
1464 Students
Step-by-step explanation:
10% increase of 1000 = 1100 year 1
10% increase of 1100 = 1210 year 2
10% increase of 1210 = 1331 year 3
10% increase of 1331 = 1464 year 4

How do I solve this problem
Answer:
-6
Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
It is asking for the base. The base is -6. The exponent is 2. The exponential form would be -6^2.
I have added an attachment so you can understand better.
They are substituing the exponent b= 5 and the base a= 2
it would be 2x2x2x2x2

Estimate (eye-ballin'): around (3, 3)
Calculation: (2.6, 3.2)
Step-by-step explanation:
Given:
4x + 3y = 20
y = 2x - 2
Sophia's strat is absolutely correct. She makes two equations into one. This is called "substitution":
- Insert y of 2nd equation as y in 1st equation:
4x + 3(2x - 2) = 20
**Remember to multiply the entire thing by 3**
4x + 6x - 6 = 20
**Solve for x**
10x - 6 = 20
10x = 26
x = 2.6
Now that we have x, just plug it into any equation to find y (hint 2nd is easier):
y = 2(2.6) - 2
y = 3.2
COORDS: (2.6, 3.2)

what is the quotient of 267.72 and 4.6?
Why 28, 60 and 120. tell me each step please?
Answer:
down here
Step-by-step explanation:
Exterior angles is the sum of the two opposite angles
so 100 - 72° = x
x = 28°
thats how you get 28°
720° is the sum of angles in a regular hexagon
720 / 6 = 120°
So the interior is 120°
To find the exterior angle, simply subtract the interior degree from 180.
external degree = 180 - 120 = 60
The exterior angle of a regular hexagon is 60 degrees.
Step-by-step explanation:
Alright, so over here, the triangle is called an exterior angle. When there is a line outside the triangle.
And the line outside the triangle means that the line outside is equal to the 2 other angles.
So in this case, it would be 100 = 72 + x.
Now let's do 100 - 72 to get the missing x.
100 - 72 is 28, right?
So our answer is 28.
Now the next one.
Regular hexagons interior angle sum using the formula (n-2) × 180 = (6-2)×180 = 4 × 180° = 720°
every interior angle then would be 720/6 = 120°
Now exterior angles are always 360°
so all angles = 360/6 = 60º.

Answer:
y = [-½]x + [-5]
Step-by-step explanation:
Equation describing how x and y are related can be written in slope-intercept form, y = mx + b.
m = slope = ∆y/∆x
Using two pairs of values from the table, (-2, -4) and (0, -5),
Slope (m) = (-5 - (-4))/(0 - (-2)) = -1/2
m = -½
b = y-intercept = the value of y when x is 0 = -5
b = -5
✔️To write the equation, substitute m = -½ and b = -5 into y = mx + b
Thus:
y = [-½]x + [-5]

Answer:
70 stones
Step-by-step explanation:
since there are 40 seashells represented by 4 in the ratio
you can do 7 times 10 and that equals 70.
