The value of 28 tens is basically doing 28 times 10(in case you didn't know). 28 times 10 is 280. So the value of 280 tens is 280.
<span>Triangle ADC is also a right triangle, with D the right angle, and AC the hypotenuse. </span>
<span>The triangles are similar (right triangles which share an angle (A), so... </span>
<span>AD/AC = AC/AB </span>
<span>5/6 = 6/AB </span>
<span>AB = 6*6/5 = 36/5 = 7.2 </span>
<span>The answer to the first question is "C" </span>
<span>CD can be found using the Pythagorean theorem... </span>
<span>AD^2 + CD^2 = AC^2 </span>
<span>25 + CD^2 = 36 </span>
<span>CD^2 = 11 </span>
<span>CD = sqrt(11) = 3.3 </span>
Simplifying
2(3(4 + p) + p) + p
2((4 * 3 + p * 3) + p) + p
2((12 + 3p) + p) + p
Combine like terms: 3p + p = 4p
2(12 + 4p) + p
(12 * 2 + 4p * 2) + p
(24 + 8p) + p
Combine like terms: 8p + p = 9p
24 + 9p
