Answer:
Step-by-step explanation:
Remark
This is a regular pentagon. The information given is enough the find the area of 1 triangle. There are 5 such triangles. So find the area of 1 of the triangles. The answer will be 5 times as much.
Givens
b = 18.3
h = 12.6
Formula
1 triangle = 1/2 * b * h
5 such triangles = 5 times as much
Solution
Area(1_triangle) = 1/2 * 18.3 * 12.6
Area (1_triangle) = 115.29
Answer: 5 * 115.29
Answer: 576.45
Answer:
a is the answer
Step-by-step explanation:
a is the answer because the way they are being multiplied are consistent, while the others arent.
Answer: The correct option is option third .
Explanation:
The given equation are,
In the second equation the like terms are aligned, therefore, we have to aligened only first equation.
The first equation is,
Subtract 0.8 from both the sides.
Add 0.4y on both the sides.
So, after aligned the system of equation have two equations.
Both equation are show in third option, So third option is correct.
Look at the picture I added
The expression is Irrational
Because one of the terms is irrational
