Answer:
Y = 2
Step-by-step explanation:
Solve for Y:
(3 + 5)×2 Y = 5×8 - 2×4
3 + 5 = 8:
8×2 Y = 5×8 - 2×4
5×8 = 40:
8×2 Y = 40 - 2×4
-2×4 = -8:
8×2 Y = -8 + 40
8×2 = 16:
16 Y = 40 - 8
40 - 8 = 32:
16 Y = 32
Divide both sides of 16 Y = 32 by 16:
(16 Y)/16 = 32/16
16/16 = 1:
Y = 32/16
The gcd of 32 and 16 is 16, so 32/16 = (16×2)/(16×1) = 16/16×2 = 2:
Answer: Y = 2
Answer:
The third choice: g(x) = (x + 3)²
Step-by-step explanation:
When translating left, you add the units shifted to x, so instead of x, we have (x + 3)
You need to use the steps of a^2+b^2=c^2
A and B are the legs. C is the hypotenuse.
If we follow that through, we find the answer is 20.
Distance = speed x time
speed = distance/time
time = distance / speed
400m/36s = 11 1/9 m per second
Let us consider the number of edges = x
we know that a triangle will have 3 edges and a square will have 4 edges. Using this details we can form an equation.
3x + 4x = 8484
7x = 8484
x = 8484/7
= 1212
Then
Number of square tiles = 1212/4
= 303
So there are 303 square tiles in the box. I hope the procedure is clear enough for your understanding. You can always use this method for solving similar problems.
