Answer: 4xy and 3xy are, 2s and 5s are, but -10 and -10b aren't.
Step-by-step explanation: 4xy and 2xy have the same terms. 2s and 5s have the same terms but -10a and -10b have different variables.

Remember that an exponent means repeated multiplication.
The exponent of 4 means you have four 
's mutiplied together:
And then each exponent of 2 inside means you have two 
's multiplied inside each set of parentheses.:
There are 8 b's there when you expand this out.
The approximate area in square feet of the sides panel is 146.4 feet.
<h3>
Area = 1 / 2 bh</h3>
where
b = base
h = height
Therefore, let's find the height and the base using trigonometric ratios.
sin 30 = opposite / hypotenuse
sin 30° = h / 26
cross multiply
h = 26 × 1 / 2
h = 13 ft.
Let's find the base using Pythagoras theorem.
b² = 26² - 13²
b² = 676 - 169
b = √507
b = 22.5166604984
b = 22.52 ft
Area = 1 / 2 × 22.52 × 13
Area = 292.76 / 2
Area = 146.38 ≈ 146.4 ft

To find the answer of the first one, plug in numbers for x, and see if they make the inequality true. Like, 5, 6, and 7.
For the second one, add 13 to both sides. The answer is 21.
