Answer:
17x+4=123(alternate angle)
17x=123-4
17x=119
x=7
The three really doesn't mean anything. the only thing the 3 stands for is how many times you have to multiply 0.25 . so in this situation you have to multiply 0.25 3 times.
this is how you do it when you get problems with exponents. this is the work /answer : 0.25×0.25×0.25=0.015625
Answer:
(9b + 3c + 10d)cm
Step-by-step explanation:
Given the sides of a triangle expressed as (2b+c), (7b + 4d) and (6d+2c). The perimeter of the triangle is the sum of all the sides of the triangles.
Perimeter of the triangle = 2b+c + 7b+4d + 6d+2c
Perimeter of the triangle = 2b + 7b + c + 2c + 4d + 6d
Perimeter of the triangle = 9b + 3c + 10d
Hence the perimeter of the triangle is (9b + 3c + 10d)cm
