Answer:

Step-by-step explanation:

The first step is to add -5 to both sides:

The next step is to divide 3 on both sides:


1.09÷3= .3633 each
4.49÷12= .37416 each
8.78÷24= .3658 each
so the first one
1/2*3*4=6
Explanation:
The height is 3 cm and the base is 4cm.
I believe 5 is there to trick you. The bottom Is always the base and the straight line going vertically is always the height.
1/2*3*4=6
Steps to simplify:
(2x + 3)(x - 7)
~Use FOIL to multiply
(2x * x) + (2 * -7) + (3 * x) + (3 * -7)
~Simplify
=2x² - 14x + 3x - 21
~Combine Like Terms
2x² + (-14x + 3x) - 21
~Simplify
2x² - 11x - 21 (Option 2)
Best of Luck!
