Answer:

5x^{-10}z^{10

Step-by-step explanation:

Given

\frac{15x^{-3}z^5}{3x^7z^{-5}}

Required

Evaluate

\frac{15x^{-3}z^5}{3x^7z^{-5}}

Start by dividing 15 by 3

\frac{5x^{-3}z^5}{x^7z^{-5}}

Apply the following law of indices on indices x and z

\frac{a^m}{a^n} = a^{m-n

So, the expression becomes:

5x^{-3-7}z^{5-(-5)

5x^{-3-7}z^{5+5

5x^{-10}z^{10

Pls answer asap 30 points<br> Solve the following equation for r : x=−3+8r5
Margaret [11]

Around 90% of the time, you'll get joke answers or answers from bots. Even if I report their answers, they will report my question back? Even though their answers are completely irrelevant to my questions? Also, your moderators are probably 12 years olds, because why? THEY. DELETE. EVERY. CORRECT. ANSWER. I. MADE. Not to mention, that there are a bunch of other users that started grouping and bullied me with vulgar words. Disgusting. Is this what your moderating has become, Huh? Brainly? IS THIS WHAT YOU CALL A PEACEFUL FRIENDLY WEBSITE FOR EVERYONE? Shame on you, I will not use this website again, until you fix your moderation "ENTIRELY".

Work out the value of A
Mkey [24]

Answer:

that is really so difficult ? what do you not understand here ? please let me know, if you need any further explanations.

you know what the perimeter is ? if it's the circumference, the way around the object. in other words, the distance you have to walk, when going along all sidelines of the object.

so the perimeter is the sum of of all side lengths.

56 = x - 1 + 3x + 3x + 1 = 7x

x = 8

that gives us the side lengths :

x - 1 = 7 cm

3x = 21 cm

3x + 1 = 22 cm

the formula for the area of a triangle

A = baseline × height / 2

the advantage of a right-angled triangle in this regard is that the sides enclosing the 90 degree angle are already "acting" as baseline and the height (standing on the baseline with a 90 degree angle).

so, we can simply say here, the 3x side is the baseline, and the x-1 side is also the height.

therefore,

A = 21×7/2 = 147/2 = 73.5 cm²

HELP ASAP
vova2212 [387]

Answer:

1. A. 4 terms

There are 4 different values in the expression, so therefore there are 4 terms.    

2. D. 3x^2 + 6x + 10

To get the answer...

start with the original expression: 3x^2 + x + 10 + 5x

add the like terms together, in this case you'd add x + 5x

you'll get: 3x^2 + 6x + 10

I hope I could help :)
