Y = 20x
y • x = 180
180/x = y
180/x = 20x
180 = 20x^2
x^2 = 6
x = + or - 3
Therefore y must equal + or - 60.
Answer:
-10 HAPPY TO HELP ILY <3
Step-by-step explanation:
The answer is 15r to the 2nd power -14r - 8, so the answer is D).
15r to the 2nd power - 20r + 6r - 8 ( I Used the FOIL method)
15r to the 2nd power + (-20r + 6r) - 8 (Gather like terms)
15r to the 2nd power - 14r - 8 (Simplify)
Answer:
a=27.1
Step-by-step explanation:
We're given both b and c of the Pythagorean formula, hence we work backwards to find A:
Answer:
The smallest amount by which the new number can exceed the original number is 23
Step-by-step explanation:
First, is necessary to identify that in a number ABCD, there are A thousands, B hundreds, C tens and D units, so the smallest number WXYZ that we obtain when we increasing exactly 2 digits by 2 and 3, is when we increase units by 3 and tens by 2. Then every digit of the the smallest number WXYZ would be:
W=A
X=B
Y=C+2
Z=D+3
Taking into account that A, B, C and D doesn't exceed the number 6, W,X,Y or Z does not exceed number 9. So the smallest WXYZ minus ABCD is:
_ A B C+2 D+3
<u> A B C D </u>
0 0 2 3
Finally, the smallest amount by which the new number can exceed the original number is 23
