Answer:
16 = 3x
Step-by-step explanation
Find the diagram attached.
Perimeter = sum of all its sides
Sum of all its sides= x+x+x
Sum of all its sides = 3x
Given perimeter = 16in
Equating both;
3x = 16
x = 16/3
x = 5.33in
Hence the value of x is 5.33 and the required equation is 16 =3x
Answer:
17. x = y^2 - 2ay +a^2
18. x = y^2 - a
Step-by-step explanation:
17. Since we want to make x the subject of the formula, we first isolate the square root of x and get
= y - a.
squaring both sides,
x = y^2 - 2ay +a^2
18. Since both x and the a are under the square root, we first start by squaring both sides.
So y^2 = x+a.
Isolating the x, we get
x = y^2 - a
