Answer:
Step-by-step explanation:
x^2 + 24x + 144 is a perfect square: (x + 12)². The square root of this is
±(x + 12).
g(x) = square root of x^3 -216 = √(x^3 - 216), or
√(x³ - 6³). x³ - 6³ is not a perfect square, altho' it can be factored.
Answer:
t = 100 minutes, or 1 hr, 40 minutes
Step-by-step explanation:
5/15 of 1 hour is the same as 5/15 of 60 minutes, which is 20 minutes
you can set up a proportion of hw completed / minutes = hw completed / min:
(1/5 ÷ 20) = (1 ÷ t) we use '1' to indicate all homework (or 100% of hw) and 't' to indicate time required
cross-multiply to get:
20 = 5/t
t = 100 minutes, or 1 hr, 40 minutes
<span>1. </span><span>The Given problem is to find
where to place the decimal point to the product shown below.
3.9853 x 8.032856, notice that the given equation are decimal numbers with both
ones place value of the whole number.
Now, given the answer 32013341 without decimal point, let’s find where to put
the decimal point.
=> 3.9853 x 8.032856
=> 32.013341
Thus, the decimal point is now located after the 2nd number. We now have 2 whole numbers with value of
tens.

7v² - 47v + 30
7v² - 5v - 42v + 30 split the second term into two terms.
v(7v - 5) - 6(7v - 5) factor out common terms in the first two terms, then the last two terms.
(7v - 5)(v - 6) << is your answer
hope this helps, God bless!
