and
we are done
Answer:
- yes, as written
- no, as simplified
Step-by-step explanation:
The equation can be simplified by subtracting 2x² from both sides. Doing that leaves a linear (not quadratic) equation:
y = 3x
__
A quadratic equation is a polynomial equation such that the exponents of the variables in a term have a maximum total of 2. Here, the terms 2x² match that requirement, making this a quadratic equation.
Answer:
The associative property states that you can add or multiply regardless of how the numbers are grouped.
Step-by-step explanation:
3+4+9=9+3+4=4+9+3 etc
Answer:
-6(a + 8) = -6a - 48
4(1 + 9x) = 4 + 36x
6(-5n + 7) = -30n + 42
(9m + 10) * 2 = 18m + 20
(-4 - 3n) * -8 = 32 + 24n
8(-b - 4) = -8b - 32
Solve all with Distributive Property of Equality.
Answer:


Step-by-step explanation:
As a mixed fraction, There are 3 circles with 5 pieces in each so our denominator will be 5
The number that is shaded is 2 whole circles so that is 10 and 2 out of 5 of last one.
The whole number is 2 and the fraction for the last circle is 2/5 so our mixed number is

Now to find the improper fraction turn 2 into a fraction with 5 as a denominator.

Which equal

Then add 2/5 to 10/5
