Answer:
Step-by-step explanation:
what we need to do is distribute the - sign in the middle of the parentheses into (7x^2 - 7 -8x^3)[/tex], this is very important to ensure we have the correct answer. by distributing we get the following equation:
now we combine like terms to get our answer
stays as it is, since there is nothing to combine it with
7x³ + 8x³ = 15x³
3x² - 7x² = -4x²
7 stays the same because like , there is nothing else to combine it with
we have the following new equation:
Number 1 is B
Number 2 is also B
Answer: the area is 20 square centimeters.
Step-by-step explanation:
The area of an arc of angle x in a circle of radius r is:
A = (x/3.14)*3.14*r^2 = x*r^2
here we have x = (4/5)*3.14 and r = 5cm
Then the area is:
A = (4/5)*(5cm)^2 = 20cm^2
C bruh I gotta add a few more characters so bla bla bla bla mathy things banana pancake
A = ((6 + 7 + 6) . 8)/2
A = 19 . 4
A = 76
