Answer: x>-2
Step-by-step explanation:
Answer:
63m^2
Step-by-step explanation:
Find the area of each base
2.5(10)= 25
1.5(10) = 15
2(10) = 20
Add them together
20 + 15 + 25 = 60
Now find the area of the triangles at each side
2(1.5)(1/2) = 1.5
Since there are two triangles, multiply the area by 2
1.5(2) = 3
Add the areas together
60 + 3 = 63
There's your answer
9514 1404 393
Answer:
6
Step-by-step explanation:
6 triangles are formed by the three diagonals through the center.
Well, whenever a number is next to a variable or next to parenthesis, (a variable is the letter[s] used to represent a value in the problem, such as 3b in this question), that means you would multiply the number times the letter, or the number times the answer in the parenthesis. So since we know a = 9, and b = 2, let's solve the equation now! :D
Now according to the order of operations of PEMDAS, let's solve what's in parenthesis first.
5(a + 3b)
⇒ a + 3b
⇒ a (a = 9), + 3 times b (b = 2)
⇒ 9 + 3 × 2
⇒ 9 + 6
⇒ 15.
⇒ 5(15)
⇒ 5 × 15
⇒ 75.
After doing all steps with the help of the order of operations of PEMDAS, your final answer would be 75. =)
I hope I helped! ^-^
