Answer:
Step-by-step explanation:
36 / 3.6 = 10
36 / 4 = 9
Answer:
b. 256
Step-by-step explanation:
Data:
W= 8
L= 8
H= 8
soln:
firstly the formula of lateral area is
LSA = (2W+2L) H
therefore:
LSA = (2×8+2×8) 8
LSA = (16+16) 8
LSA = (32) 8
LSA = 256
Answer: k < 3
Step-by-step explanation: Just like any of your two-step equations, in this inequality, start by isolating the k term which in this case is 5k by subtracting 3 from both sides. That leaves you with 5k < 15.
To get <em>k</em> by itself, divide both sides by 5 and <em>k < 3</em>.
Answer: 16
Step-by-step explanation:
Answer:
5x + 3
Step-by-step explanation:
We factor 25x^2 + 3x + 9.
25x^2 is a perfect square; 25x^2 = (5x)^2
9 is a perfect square; 9 = 3^2
This expression may be a perfect square trinomial.
25x^2 + 30x + 9 = (5x + 3)^2
We check the middle term: 2ab = 2 * 5 * 3 = 30
The coefficient, 30, is correct, so we are dealing with a perfect square trinomial.
length = 5x + 3
