The area of the trapezoid would be 48
Answer:
a, -b
Step-by-step explanation:
When x is a, the function becomes

as you see, a-a is 0, and as your whole function is multiplied by this, it makes it 0.

As you see -b+b is 0, and once again, this would make the whole function 0.
Answer:
<em>x = y = 64° , z = 20°</em>
Step-by-step explanation:
<em>x = y</em> =
<em>= 64 </em>°
m∠ADC = 52° + x
m∠ADC = 52° + 64° = 116°
<em>z</em> = 180° - 116° - 44° <em>= 20</em> °
Answer:
65
Step-by-step explanation:
If the intent of the question is to estimate, I would say do so through rounding. 12.95 is basically 13 and 5.2 is basically 5. So 13 x 5 = 65 would be a good estimate.
