♡ The Explanation/Step-By-Step ♡
・-2 (x + 7) = x -34 + 2x
-2 (x + 7) = x + 2x - 34
-2 (x + 7) = 3x - 34
-2 (x + 7) : -2x - 14
-2 (x + 7)
Apply the distributive law! : a(b + c) = ab + ac
a = -2, b = x, c = 7
= -2 + (-2) x 7
Apply minus (-) plus rules!
+ (-a) = -a
= -2x - 2 x 7
Multiply the numbers! : 2 x 7 = 14
= -2x - 14
-2x - 14 = 3x - 34
Add 14 to both sides!
-2x - 14 + 14 = 3x - 34 + 14
Simplify!
-2x = 3x - 20
Subtract 3x from both sides!
-2x - 3x = 3x - 30 - 3x
Simplify!
-5x = -20
Divide both sides by -5!
-5x/-5 = -20/-5
Simplify! : -5x/-5 : x
Apply the fraction rule! : -a/-b = a/b
= 5x/5
Divide the numbers! : 5/5 = 1
= x
Simplify! : -20/-5 : 4
-20/-5
Apply the fraction rule! : -a/-b = a/b
= 20/5
Divide the numbers! 20/5 = 4
= 4
x = 4

Answer:
f\left(x\right)=x^3-x
Step-by-step explanation:
Answer: a=3.74
Step-by-step explanation:
first use 15 to solve for x and z. x=7.5 and z=12.99 or 13. Once you know x you can use that to solve for y and a. y=6.5 and x=7.5 and using pythagorean theorem you will find that a= the square root of 14 or 3.74.
Answer:
A(-1,3),B(2,-2),C(4,5),D(-2,-5)
