To find the perimeter of a triangle, you add all the sides.
(2x +1) + (3x+2) + (x+3)
next find all the common variables
2x, 3x, and x
add them together to get
6x
Add 1,2, and 3
6
so your answer is 6x +6
Hope this helps! :)
Answer:
33.27
Step-by-step explanation:
Since it decreases by 36 each year, the change would be 36+36+36+36=36*4=144
For a, we can plug in values for t, so 2000-(200*1)=1800 for the first year,
2000-(200*2)=1600 - do you see the pattern here? It subtracts by 200 every year, so 1600-200=1400 for the third year and 1400-200=1200 for the fourth year.
Answer:
<h2>D. 76</h2>
Step-by-step explanation:
Put x = 4, y = -5 and z = 2 to the expression 3x² - 4y + xz and use PEMDAS:
3(4)² - 4(-5) + (4)(2)
= 3(16) + 20 + 8
= 48 + 20 + 8
= 76
Answer:
8/27 ≈ 29.6%
Step-by-step explanation:
Two of the six faces are B, which means four of the six faces are not B.
The probability of rolling not B three times is:
P = (4/6)^3
P = (2/3)^3
P = 8/27
P ≈ 29.6%
