Answer:

X= -10

Step-by-step explanation:

15=3x-15

Minus the numbers on the other side of the variable

15=3x-15

-15      -15

=0       -30

In algebra the - before a number gets counted as a negative so -15 minus 15 = -30

Then since we still have 3x we divide it by -30 because its being tiems by a number we cant see

so -30/3 = -10

Thats how we found X.

Answer:

Solve for x

Step-by-step explanation:

we already know that 30 minus 15 is 15 so something times 3 equals 30. 10x3=30. so x = 10.

15 =3(10)-15

15= 3(10) -15 =30 -15

15 = 30 - 15

15=15

So, again, the answer is 10.

Which expression is equivalent to this expression? x(2x+3) Question 1 options: 2x2+3 2x2+3x 2x2−3x 3x + 3
sleet_krkn [62]

Answer:

2x^2+3x is the expression which is equivalent to  x\left(2x+3\right).

In other words:

x\left(2x+3\right)=2x^2+3x

Step-by-step explanation:

Given the expression

x\left(2x+3\right)

solving

x\left(2x+3\right)

\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b+c\right)=ab+ac

a=x,\:b=2x,\:c=3

=x\cdot \:2x+x\cdot \:3

=2xx+3x

=2x^2+3x            ∴  2xx=2x^2

Thus,

x\left(2x+3\right)=2x^2+3x

Therefore, 2x^2+3x is the expression which is equivalent to  x\left(2x+3\right).

A graph is constructed of the length of the side of a square compared to the area of a square. what would the function rule be t
sergeinik [125]
Based on the given description above, it is said that the graph is made of the length of the side of a square. By definition, a square has equal sides, and the area of getting the square is A=s^2. Therefore, the function rule for this to find the area for any given side length would be y = x^2. Given the y is the area of the graph and x is the length of the side. Hope this answer helps.
