Answer:
The value of x = 18
===============================
Step-by-step explanation:
Given m∠A = 2x + 4
m∠B = 6x - 58
The exterior angle at C = 5x
We should know that:
The exterior angle at C = m∠A + m∠B
∴ 5x = (2x + 4) + (6x - 58)
Solve for x
∴ 5x = 2x + 4 + 6x - 58
∴ 5x = 8x - 54
∴ 5x - 8x = -54
∴ -3x = -54
∴ x = -54/-3 = 18
<u>So, the value of x = 18</u>
Answer:
6f + 3
Step-by-step explanation:
so in order to get a equation that is equivalent to 4f + f2 + 3 is you have to simplify the expression by adding numbers to numbers and variables to variables.
so we are going to add 4f and 2f together:
(4f + f2) + 3
And you get the expression:
6f + 3
I hope this helps you!!
Answer:
Step-by-step explanation:
hello :
B. (x − 4)(x + 9)
calculate : (x − 4)(x + 9)= x²+9x-4x-36 = x²+5x-36
I would go with the answer B
Answer:
0
Step-by-step explanation:
We are given that each electron in an atom has a charge of -1 and each proton has a charge of +1.
The charge of 2 electrons will be:
2 * (-1) = -2
The charge of 2 protons will be:
2 * 1 = 2
The overall charge is the sum of the charge of the 2 electrons and the 2 protons. That is:
-2 + 2 = 0
The overall charge is 0.
