<span>Note that -6.8 = -1*6.8. Therefore (-6.8)2 = (-1)*6.8*2. The product of 6.8*2 is 13.6. Hence (-6.8)2 = (-1)*13.6 = -13.6.</span>
Answer:
166 mm²
Step-by-step explanation:
The area is given by ...
A = (1/2)Pa . . . . . where P is the perimeter and "a" is the apothem
One side of a 6-sided figure is shown as 8 mm, so the perimeter is ...
P = 6·(8 mm) = 48 mm
Filling in the apothem value, we have ...
A = (1/2)(48 mm)(4√3 mm) = 96√3 mm² ≈ 166 mm²
The area of the hexagon is about 166 mm².

Answer:
3x^2 + 7x - 5 + 2x^2
= 5x^2 + 7x - 5 (a=5, b=7, c=-5)
x = (-b+/- √(b^2 - 4ac))/2a
= (-7+/- √(49+100))/10
= (-7+√149)/10, (-7-√149)/10
Hope this helps!
Answer:
b) It is a binomial with a degree of 3.
Step-by-step explanation:
We need to find about which is true about the polynomial –3xy2 + 5x2y from the given choices.
There are two terms so it is binomial.
Sum of exponents of variables in first term = 1+2=3
Sum of exponents of variables in 2nd term = 2+1=3
Highest exponent on variable is 3 so degree is 3.
Correct matching choice is "It is a binomial with a degree of 3."
Hence final answer is choice "b) It is a binomial with a degree of 3."
