220
This should be correct since you are multiplying by 2
Answer:
a. 7x^2-15=32x
Step-by-step explanation:
a standard form quadratic equation is written as ax^2+bx+c=0
7x^2-15=32x can be rewritten into 7x^2-32x-15=0 by subtracting 32x on both sides.
options b and c don't work because they include another variable, y
option d is a linear equation, not a quadratic
Distributive property is taking the number in front of the parentheses and multiplying every term in the parentheses by the number.
So in 4(5 +3),
Multiply 5 and +3 by 4.
4 * 5
20
4 * 3
12
20+12
32
For the second equation do the same thing. Multiply 22 and -6 by 2.
22 * 2
44
-6 * 2
-12
44 + -12
32
32 = 32
