Answer:
1400
Step-by-step explanation:
it will be easier to first do 30 times 60, which is 180, then subtract the parts
the left up part is 100, the left bottom is 150, the top right is 150, added together, is 400
1800-400
Answer:
Break down the problem into these 2 equations.
a+6=3a+2
a+6=3a+2
a+6=2a
a+6=2a
Solve the 1st equation: a+6=3a+2a+6=3a+2.
a=2
a=2
Solve the 2nd equation: a+6=2aa+6=2a.
a=6
a=6
Collect all solutions.
a=2,6
a=2,6

Answer:
90
Step-by-step explanation:
Answer:
- Powers of the variable descending left to right
- right side of the equal sign is 0
Step-by-step explanation:
For some constants a, b, and c, the standard form* is ...
ax^2 + bx + c = 0
___
It is nice if the leading coefficient (a) is positive, but that is not required.
The main ideas are that ...
- Powers of the variable are descending
- All of the non-zero terms are on the left side of the equal sign
- Like terms are combined
_____
* This is the <em>standard form</em> for a quadratic. For other kinds of equations, when the expression is equal to zero, this would be called "general form."
