Given:
ΔABC is an equilateral triangle.
AB = 7.5x, BC = 6x + 3 and CA = 10x - 5
To find:
The value of x.
Solution:
In equilateral triangle, all sides are equal.
AB = BC = CA
Take any two sides only:
AB = BC
Subtract 6x from both sides.
Divide by 1.5 on both sides.
The value of x is 2.

Answer:
5/6
Step-by-step explanation:
There are 5 squares of dimensions 3 x 3.
5 x (9) = 45 sq. in.
There are 4 right triangles of leg lengths of 6.
4 x (18) = 72 sq. in.
45 + 72 = 117 sq. in.
Answer:
3(3 +4n)
OR
9 + 12n
Step-by-step explanation:
9 + 12n
Factorize it
3(3 +4n)
OR
The answer is the same.
Since we can't add a number with a number and letter. So in that case the answer is ;
9 + 12n.
