Answer:
- n is equal to <u>3 </u><u>meters</u>
Step-by-step explanation:
In this question we are provided with a cube having <u>volume </u><u>2</u><u>7</u><u> </u><u>cubic </u><u>meters</u><u> </u>. And we are asked to find the <u>value </u><u>of </u><u>n </u>that is basically its <u>edge </u><u>.</u>
For finding the value of n we need to know the volume of cube. So ,

<u>Where</u><u> </u><u>,</u>
- a refers to <u>edge </u><u>of </u><u>cube</u>
<u>SOLUTION</u><u> </u><u>:</u><u> </u><u>-</u>
Substituting given volume that is 27 m³ and value of a as n in formula :

Applying cube root on both sides :
![\quad \longrightarrow \qquad \: \sqrt[3]{n {}^{3} } = \sqrt[3]{27}](https://tex.z-dn.net/?f=%20%5Cquad%20%5Clongrightarrow%20%5Cqquad%20%5C%3A%20%20%5Csqrt%5B3%5D%7Bn%20%7B%7D%5E%7B3%7D%20%7D%20%20%3D%20%20%5Csqrt%5B3%5D%7B27%7D%20)
We get ,
![\quad \longrightarrow \qquad \:n= \sqrt[3]{27}](https://tex.z-dn.net/?f=%20%5Cquad%20%5Clongrightarrow%20%5Cqquad%20%5C%3An%3D%20%20%5Csqrt%5B3%5D%7B27%7D%20)
We know that 3 × 3 × 3 is equal to 27 that means cube root of 27 is 3 . So ,

- <u>Henceforth</u><u> </u><u>,</u><u> </u><u>value</u><u> </u><u>of </u><u>n </u><u>is </u><u>❝</u><u> </u><u>3 </u><u>meters </u><u>❞</u>
<u>Verifying</u><u> </u><u>:</u><u> </u><u>-</u>
Now we are checking our answer whether it is wrong or right by substituting value of n and equating it with given volume that is 27 cubic meters . So ,
- a³ = 27 ( where a is equal to n )
Substituting values :
<u>Therefore,</u><u> </u><u>our</u><u> answer</u><u> is</u><u> correct</u><u> </u><u>.</u>

Answer:
60°
Step-by-step explanation:
Given :
DAB= (180 – 3x) °,
mZ B= (6x – 40) °, and
m ZC = (x+20) °.
DAB = mZ B + m ZC ( the exterior angle equal the sum of the two opposite interior angles)
180 - 3x = (6x - 40) + (x + 20)
180 - 3x = 6x - 40 + x + 20
180 - 3x = 6x + x - 40 + 20
180 - 3x = 7x - 20
180 + 20 = 7x + 3x
200 = 10x
x = 200/10
x = 20
Angle B = 6x - 40 = 6(20) - 40 = 120 - 40 = 80
Angle C = x + 20 = 20 + 20 = 40
BAC = 180 - (80 + 40) (SUM OF ANGLES IN A TRIANGLE)
BAC = 180 - 120
BAC = 60°
Answer:

Step-by-step explanation:
Completing the square is a multi-step process that involved rewriting an equation such that it has a factored term, a coefficient, and a constant. First, group the equation, then add a term such that the grouped part of the equation can be simplified, then balance the equation, finally simplify and factor the equation.

Group;

Add in a term that makes the grouped part of the equation a perfect square, this can be done by dividing the linear term by 2, then balancing the equation;

Simplify, factor;
