Answer:
x=49
Step-by-step explanation:
The equation would be x+3x(10+2x)=142
The sides are 22cm , 54cm and 66 cm.
It is written as 0.00017 in ordinary form.
Dependent variable is the variable that changes due to the independent variable, independent variable is the variable that scientists change on purpose.
Equation 1) 10x + 2y = 30
Equation 2) 4x + y = 4
Multiply all of equation 2 by 2.
2) 2(4x + y = 4)
2) 8x + 2y = 8
1) 10x + 2y = 30
Subtract equations from each other.
-2x = -22
Divide both sides by -2.
x = -22/-2
x = 11
B) x = 11
