Answer:
The values of a and b are a = 11 , b = 7
Step-by-step explanation:
* Lets explain how to solve the problem
* In the exponential functions we have some rules
1- In multiplication if they have same base we add the power
# Ex: b^m × b^n = b^(m + n) ⇒ b is the base , m and n are the powers
2- In division if they have same base we subtract the power
# Ex: b^m ÷ b^n = b^(m – n) ⇒ b is the base , m and n are the powers
3- If we have power over power we multiply them
# Ex: (b^m)^n = b^(mn) ⇒ b is the base , m and n are the powers
* Lets solve the problem
∵ The equation is ⇒ (1)
- At first multiply the coefficients
∵ -4 × 5 = -20
- Multiply the base x
∵
- Multiply the base y
∵
∴ ⇒ (2)
- By comparing (1) and (2)
∴ a = 11 and b = 7
* The values of a and b are a = 11 , b = 7
The perimeter of a triangle is side a + side b + side c. so...
(2x + 4) + (2x + 4) + (2x + 4) = 6x + 12.
But if you need to go farther...
6x = -12
x = -2
then replace x in the original equation with -2......
2(-2) + 2(-2) + 2(-2)
multiply
(-4) + (-4) + (-4)
add
the answer should be -12
Okay, so these problems can be quite tricky because a lot of it is remembering little rules but let me tell you how you can figure out this one! :)
Also just a little warning is that I'm not quite good at remembering the math terms for different parts so please don't mind that :P
Alright, since G is the centroid then it is in the middle of BE! That means segment BE is cut into two different parts! A 1/3 part and a 2/3 part. You can probably tell by looking which part is which because 1/3 is less than 2/3.
Hopefully you get what I'm saying so far :)
Now since you know there are two parts (a 1/3 and 2/3 segmet of BE). You can just figure each of them out considering you know BE's whole length! So 1/3 of 9 is 3 and 2/3 of 9 is 6. SO the 1/3 section is equal to 3 and the 2/3 section is equal to 6!!!! Now you practically have your answer right there!
Notice that the bigger part is segment GE (the 2/3 part) and the smaller part is BG (the 1/3 part). Since you know the 1/3 and 2/3 equal and what segment they are you have the answer!
BG = 3 and GE = 6
I really hope that helps! ^-^ Let me know if you have any questions! :3
