These numbers are called power of ten. A power
of ten is 10 multiplied by itself the exponent number of times. For example:
We can write 10 as 10¹
100 as 10²
1000 as 10³
<span>The exponent is equal to the number of zeros in
the number like 100 has 2 zeros so the exponent is 2 and write it as 10</span>²

Answer:
<em>A)</em> The answer is D, 8a + 5
4a + 5 + 4a
we simplify this expression(combine like terms):
group them first;
(4a + 4a) + 5
8a + 5
<em>B)</em> 2c + 6 + 3c - 4
simplify this expression (combine like terms):
group them first;
(2c + 3c) + (6 - 4)
5c + 2
Answer:
<h2>See the explanation.</h2>
Step-by-step explanation:
(a)
Total number of degree recipients are 3831.
From 3831 recipients, 1 can be chosen in 
ways.
Among the 3831 recipients, total number of male is 1574.
Similar as above, 1 male can be chosen in 1574 ways.
Hence, the probability of the chosen person being a male is 
≅ 0.4109.
(b)
Total males are 1574 in number.
Among them 326 males have done masters.
The probability of the chosen male has done masters is 
≅ 0.2071.
(2x^2 +6x) + (5x +15)
GCF for the 1st group is 2x and the 2nd is 5
2x(x +3) + 5(x +3)
(2x +5) (x+3)
