For the regular sequence 1, 2, 3, ...,
, then sum is
If we multiply each number by 7 (7, 14, 21, ...), then the sum is
and if we add 1 to each number (8, 15, 22, ...) then the sum is
We have
terms, so the sum is:
I think it’s 22 minutes because it says that George take 1 hour longer than Henry to mow a lawn. When they work together, it takes them 1 hour and 12 hours, do 1 hour and 12 minutes - 1 hour is 12
Answer:
avion

Answer:
B
Step-by-step explanation:
<em>a/b × d/c = a×d / b×</em><em>c</em>
Multiply the numerators 1st.
x × x = x^2
Next is the Denominator.
x+3 × x+2
now try to multiply each term of the 1st expression with the 2nd.
x × x + x × 2 + 3 × x + 6
x^2 + 2x + 3x + 6
x^2 + 5x + 6
Write the numerator & denominator in their respective places.
x^2 / x^2 + 5x + 6
