Answer:
perimeter = sum of all sides. this is same for polygons
rect: area l×b. peri = 2(l+b)
Step-by-step explanation:
15+5 = 20
20*2 = 40 cm is the perimeter of the given figure
Answer:
D
Step-by-step explanation:
The parent graph (red) is y = x^2
To get that graph to move right 4 units, the graph become y1 = (x - 4)^2
To get the graph to move up 1 unit, add 1 on the right. y2 = (x -4)^ + 1
The answer is D
Note: getting a graph to move left or right is a bit anti-intuitive. If you want it to move right, you have to subtract a number from x before before squaring the result. Your intuition would tell you to add the number, but that moves the graph left.
Answer:
the value of x is (-2) and y is (-5)
sin α = opposite leg/ hypotenuse
For ΔABC,
sin A = |BC|/|AB|
sin A = 12/37
