Desmos comes in handy with these problems. Use the "FOIL" method for each of them and then plug them into the calculator of desmos. This will graph each other them. Note the x and y axis'
Example for (A) y= (x-2)(x+3) foil it:
x^2+3x-2x-6
x^2+x-6
plug that in and match to graph.
Step-by-step explanation:
Given is rectangle with perimeter = 54 centimeters and area = 176 squared centimeters.
Let's consider the length of rectangle = L and width of rectangle = W.
We know the following formulas for rectangle :-
Perimeter = 2 x (L + W)
Area = L x W
So we have 2 x (L + W) = 54 and L x W = 176.
L + W = 27 and L x W = 176
We need to find two positive integers such that their sum is 27 and product is 176.
Using trial and error, we have two such positive integers such that 11 + 16 = 27 and 11 x 16 = 176.
So, the dimensions of rectangle would be 11cm x 16cm.
Hence, option A is correct i.e. 11 cm by 16 cm.
