M³×n=189 Find m and n

Mathematics

Answer:

m=3, n = 7

Step-by-step explanation:

Assuming m and n are integers, the following are the possible values of m and n

Let m = 1, then m³ = 1 and n= 189

If m = 2 we get 8n = 189 and 189/8 is not an integer so m ≠ 2

If m = 3, we get 27n = 189 and n = 189/27 = 7

Any higher integer values of m will not result in n being an integer and I am assuming m > 1 so the correct answer is m=3, n = 7

Drag and drop a phrase to make the statement true.

Lady bird [3.3K]

A similar because all triangles add up to 180 ,

they both have 80 so leaves 100 degrees left..

and they both have the same #'s 80, 60, & 40 degrees equal to 180 degrees

Find the missing terms in each geometric sequence

aksik [14]

Answer:

3, <u>36</u>, 108

Step-by-step explanation:

Can't tell you if that is definitely correct, but I tried. All I did was try to figure out the common ratio for each sequence.

E.g. 3x36 = 108.

Which equation has solution x = -3?

vladimir1956 [14]

Hi Brainiac

1/2(2x-6) = -6
We need to distribute
(1/2)(2x) + (1/2)(-6) = -6
2x/2 + -6/2 = -6
x - 3 = -6
x = -6 + 3
x = -3
Thus, The answer is D

I apologize for the late answer :(

Choose the correct simplification of the expression (8x − 5)(2x2 − 5x − 6). 16x3 − 50x2 − 23x − 30 16x3 − 50x2 − 23x 30 16x3 − 3

The correct simplification of the given expression is (B) $16x^{3} -50x^{2} -23x+30$ .

<h3>What is an expression?</h3>

An expression or mathematical expression is a finite combination of symbols that is well-formed according to context-dependent norms.

To find the correct simplification of the given expression:

The easiest terms to check are the first (8x)(2x²) = 16x³ and the last (-5)(-6) = 30.
This check eliminates the first choice.
The remaining choices differ only in the sign and coefficient of the squared term, so that is the one we need to find.
The squared term will be the sum of the products of factors whose degrees total 2:
$(8x)(-5x)+(-5)(2x^{2} )=-40x^{2} -10x^{2} =-50x^{2} =16x^{3} -50x^{2} -23x+30$

Therefore, the correct simplification of the given expression is (B) $16x^{3} -50x^{2} -23x+30$ .
