Answer:
$26,250
Step-by-step explanation:
$3,500×(2.5)^3
Answer: B
Step-by-step explanation: I know
The equation given to us is called a literal equation. An equation made up of a whole bunch of different variables. If we need to isolate the l, we first have to get it out from inside that set of parenthesis. Do that by distributing the 2 in to get P = 2L + 2w. We will subtract 2w from both sides to get P - 2w = 2L, and then we have to divide everything by 2 to get L alone. That leaves us with
. That is also the same thing as
, whichever one you want. Now, solving 4w - 7k = 28 for k requires that we subtract 4w from both sides leaving us with -7k=28-4w. Now we divide everything by -7 and we end up with
, which is also the same thing as
if you don't like to start with a negative.
Step-by-step explanation:
quick ...
first we need to find x.
and then we can calculate the area by
baseline × height / 2
which is here
12 × x / 2
x we get via Pythagoras
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90 degree angle).
15² = 12² + x²
x² = 15² - 12² = 225 - 144 = 81
x = 9
the area of the triangle is then
12 × 9 / 2 = 6×9 = 54 m²
