The vol. of a cube of side length s is V=s^3.
So, if the side length is 5a+4b, then the volume of the cube is
V(a, b) = (5a+4b)^3. This could, of course, be expanded, using the binomial theorem, but there's no point in doing so.
800-20 is 780. A third of 780 is 780(1/3) = 260. 780 - 260 = 520. 25% of $520 is 0.25(520) = 130. 520 - 130 = 390. One sixth of 390 is 390(1/6) = 65. 390 - 65 = 325. So, Bob kept $325 for himself.
Answer:
Step-by-step explanation:
First you will divide I-2xI on both sides that should look like this:
-2x/-2 = 10/-2
when you divide it your -2‘s should cancel out and you should be left with
-x=10/-2
when You divide 10/-2 you should get -5
10/-2= -5
your answer should look like this then
-x=-5
-5 is just one of your answers the other is 5
To get rid of the negative on the -X you have to didvide it by both sides
-x/-x=-5/-x
your answer should be
X= 5
your final answers are
-5 or 5
Given that ΔLMN and ΔPQR are congruent triangles, therefore the corresponding parts are:
<h3>What are Congruent Triangles?</h3>
Congruent triangles has three pairs of congruent sides and three pairs of congruent angles that corresponds to each other.
Thus, given that, ΔLMN ≅ ΔPQR:
- LM ≅ PQ
- QR ≅ MN
- LN ≅ PR
- ∠L ≅ ∠P
- ∠M ≅ ∠Q
- ∠N ≅ ∠R
Therefore, given that ΔLMN and ΔPQR are congruent triangles, therefore the corresponding parts are:
