Answer:
37 and 39
Step-by-step explanation:
True, this is a Pythagorean identity.
The last one
You’re completing the square here so you have to find (1/2b)^2. In this case it’s 1. So you have to add 1 to both sides. Then you have to solve for it
It becomes
(x-1)^2 = -7
Then you have to find the square root
(x-1) = √-7
x-1 = √7 √-1
x-1= ± i √7
x= 1 ±i √7
That’s your answer and d is the only one that matches with it
Answer:
The answer is
B. 6m²
Step-by-step explanation:
N/B: the drawing was not provided, so kindly find attached the drawing for your reference.
We know that the area of a rectangle = length *breath
From the diagram the rectangular surface has a length l=3m
Breath b=2m
Area = 3*2= 6m²
