Un grouping in 3rd grade maths can also be called subtracting
Answer:
C. 184 ft²
Step-by-Step Explanation:
The formula for the surface area of a triangular prism is
SA = bh + 2ls + lb; where b = base, h = height, l = length, s = side
First, substitute the known value into the equation:
b = 6 ft
h = 4 ft
l = 10 ft
s = 5 ft
SA = (6)(4) + 2(10)(5) + (10)(6)
Then, all we have to do is simplify:
SA = 24 + 2(50) + 60
SA = 24 + 100 + 60
SA = 184 ft²
Hope this helps!
Answer: 10x + 4y + 2
The terms with an x are considered like terms so they could be subtracted.
Answer:
step 3 and step 4
Step-by-step explanation:
2(x − 4) + 6x = 9x − 10
2x - 8 + 6x = 9x - 10
2x +6x - 9x = -10 + 8
-x = -2
x = 2
It’s supposed to be (5,9) both numbers positive
