4√7
This is similar to collecting like terms in algebra
take out a common factor of √7 from each term
= √7( 5 + 1 - 2 ) = 4√7
Answer:
A=72CM^2
Step-by-step explanation:
The answer is 72cm^2 because the area of a triangle is h x b divided by two because the triangle is half of a square, since the square is side times side, the answer is 12x12 divided by two, wich is 144/2. The final answer is 72
Answer:
b i am pretty sure
Step-by-step explanation:
Answer:
please check the first question it is square or rectangle and it is saying triangle
verify it and tell in chatbox
The data has a peak at x=5, so we expect it to be modeled with a parabola that opens downward. That is the x² coefficient will be negative.
For x=1, the third choice gives a better approximation to (x, y) = (1, 32) than does the first choice. It is appropriate to choose
... y = -11.41x²+154.42x-143.9
_____
The quadratic regression function of a graphing calculator confirms this choice.
