6000N

reason: according to Newton’s second law of motion, Force = Mass x Acceleration
using this, multiply 2000 by 3 to get 6000

X is all the following except<br> a term<br> a variable<br> a constant<br> an expression

lisov135 [29]

Answer: a constant

Step-by-step explanation:

A constant is a numerical expression like 2, 0,78 etc .

A variable is a alphabetical expression that vary like a,b,c,d,x,y,z.

An expression can consists of both numerical and alphabets and also any arithmetic expression like x, 2abc, 6a+2c etc

A term consist of either numbers and variables multiplied together or only numbers or variable like 2xy, x, 2ab etc.

X is all (a term, a variable , an expression) except a constant because a constant is a numerical expression.

Which expressions are completely factored? Select each correct answer. 32y10−24=8(4y10−3) 18y3−6y=3y(6y2−2) 16y5+12y3=4y3(4y2+3)

laila [671]

Answer:

Option A and Option C

Step-by-step explanation:

Option A: $32y^{10}-24 = 8(4y^{10}-3)$ This is completely factored as 8 is the Highest Common Monomial factor

Option B: $18y^{3}-6y = 3y(6y^{2}-2)$ This is not completely factored as 2 is still a common factor of 6y2 and -2.

Option C: $16y^{5}+12y^{3}=4y^{3}(4y^{2}+3)$ This is completely factored as 4y2 is the Highest Common Monomial factor

Option D: $20y^{7}+10y^{2} = 5y(4y^{6}+2y)$ This is not completely factored as 2y is still a common factor of 4y6 and 2y.

So the options that are completely factored are Option A and Option C

Two adjacent angles form a complementary relationship. One angle is twelve more than twice the other angle. Draw a picture to re

Anon25 [30]

Answer:

The angles are 26 and 64

Step-by-step explanation:

When two angles are complementary, what this means is that the add up to 90 degrees

Now, let’s say one of the angles is x, the other angle is 12 more than twice it; mathematically that would be 2x + 12

Since they add up to be 90, we have

x + 2x + 12 = 90

3x + 12 = 90

3x = 90-12

3x = 78

x = 78/3

x = 26

The other angle is 2x + 12 = 2(26) + 12 = 52 + 12 = 64

Which inequality statement best represents the graph below?

lbvjy [14]

Graph A is correct. The ≥ sign is correct because the gray area is above the red. x^2 has a positive coefficient which corresponds to the opening-up parabola.
