Answer:
In word form - "Two and fifty-one hundredths." In expanded form - 2 + 0.5 + 0.01.
Step-by-step explanation:
To write a decimal in word form, we write out the words we would say as we read the decimal. When we read a decimal, we read the whole number before the decimal. This is "two." The decimal is read as "and." After this, we read the digits behind the decimal as a group; 51 would be read as "fifty-one", and since 1 is in the hundredths place, it is "fifty-one hundredths."
To write a number in expanded form, we separate the digits by place value. 2 is in the ones place, so it equals 2. 5 is in the tenths place, so it equals 0.5. 1 is in the hundredths place, so it equals 0.01. Together this gives us:
2 + 0.5
It is a linear simple equation, lets solve it step by step:
<span>X + 3(X + 4) = 20
x + 3x + 3*4 = 20
4x + 12 = 20
4x = 20 - 12
4x = 8
x = 8/4
x = 2</span>

Answer:
25 = 5^2
Step-by-step explanation:
Factor the following integer:
25
Hint: | Is 25 divisible by 2?
25 is not divisible by 2 since 25 is odd and 2 is even:
25 = 25 (25 is not divisible by 2)
Hint: | Is 25 divisible by 3?
The sum of the digits of 25 is 2 + 5 = 7, which is not divisible by 3. This means 25 is not divisible by 3:
25 = 25 (25 is not divisible by 2 or 3)
Hint: | Is 25 divisible by 5?
The last digit of 25 is 5, which means 25 is divisible by 5:
25 = 5 5:
25 = 5×5 (5 is not divisible by 2 or 3 since 25 is not)
Hint: | Now try to factor 5. Is 5 prime?
No primes less than 5 divide into it. Therefore 5 is prime:
25 = 5×5
Hint: | Express 25 as a prime power.
There are 2 copies of 5 in the product:
Answer: 25 = 5^2
