What is 2c+7=21

1. firstly you minus the 7 from both sides

2c+7=21
-7 -7

= 2c=14

2. Then you divide each side by two.

2c=14
÷2 ÷2

= c=7

3. Then substitute it back in:

1. 2x7 = 14
2. 14+7 =21

C=7

Hello there.

Question: What is 2c+7=21 please help

Answer: Solve the equation:
Subtract 7 from both sides:
21 - 7 = 14
2c = 14.
Divide both sides by 2:
14/2 = 7
c = 7.

A function is a rule that assigns each value of the independent variable to exactly one value of the dependent variable. True or

vesna_86 [32]

The answer is true
Let's imagine that we have the following function function:
 $y = x ^ 2 
$
We have to:
Independent variable: x
Dependent variable: y
For x = -1:
 $y = (- 1) ^ 2 = 1 
$
 For x = 1:
 $y = (1) ^ 2 = 1 
$
 We observe that the independent variable can only obtain one result.
Answer:
True

The base of a triangle is represented by (2x − 6) and the height by (x − 2). Which polynomial expression BEST represents the are

BabaBlast [244]

Area of a triangle= $\frac{1}{2} *base*height$
A= $\frac{1}{2} *(2x-6)*(x-2)$
A= $\frac{1}{2} ( 2x^{2} -4x-6x+12)$
A= $x^{2} -2x-3x+6$
A= $x^{2} -5x+6$
