4/20 = x/20 +x
80 + 4x = 20x
80/16 = x
5 = x
that being said. Is that your name???
Answer:
1. n=2
2. n=12
3. n=2
Step-by-step explanation:
1
12xy³/4xⁿy=3y²/x
12x²y³=12y³xⁿ (cross multiplied)
x²=xⁿ (cancelled out (12y³))
2=n
2
(-3a/2b⁴)³=-27a³/8bⁿ
-27a³/8b¹²=-27a³/8bⁿ (cubed left side)
-216a³bⁿ =-216a³b¹² (cross multiplied)
bⁿ=b¹² (cancelled out (-216a³))
n=12
3
(xy⁶/x⁵yⁿ)²=y⁸/x⁸
x²y¹²/x¹⁰y²ⁿ=y⁸/x⁸ (squared left side)
x²y¹²/x¹⁰y²yⁿ=y⁸/x⁸
y¹⁰/x⁸yⁿ=y⁸/x⁸ (simplified)
y¹⁰x⁸=x⁸yⁿy⁸ (cross multiplied)
y²=yⁿ (cancelled out (x⁸), simplified)
n=2
<h2>PERIMETER</h2>
==============================================
<em>the formula for perimeter of a Rectangle is this ::</em>

==============================================
Both triangles are similar because 2 angles are same, only difference is in size.
similarity theorem - 2 angles of one triangle are congruent to 2 angles of another triangle, corresponding sides are in proportional.
24/ 3x+6 = 32/28
24 x 28 = 32 (3x+6)
x = 5
