Answer:220/7 or 31.4

Step-by-step explanation:

circumference of circle= 2*pi*radius

radius= half the diameter so its equal to 10/2=5

so C=2*22/7( or 3.14)*5=220/7(or 31.4)

c= 10 π

c=  10 * π

c= 10*3.14= 31.4 cm

Can someone please explain how to solve such a mean and sneaky problem? Please?
Lelu [443]

Answer:

all real numbers

Step-by-step explanation:

simplify each side of the inequality

26 + 6b -- already fully simplified

2(3b + 4) → 6b + 8

26 + 6b ≥ 6b + 8

subtract 6b from both sides

26 ≥ 8

since this expression is true (26 is greater than 8), then the solution is all real numbers. any value could take the place of b because in the end, it will be canceled out by itself, resulting in 26 ≥ 8

What if the following is the sum of both solutions of the equation....
LuckyWell [14K]

answer

D 2

factor

factor the equation x^{2} - 2x - 8 = 0  into (x + a)  and (x + b) so that a + b = -2 and a * b = -8

the two numbers that meet these conditions are a = -4 and b = 2

x^{2} - 2x - 8 = (x - 4)(x + 2)

find solutions

set both (x - 4) and (x + 2) equal to zero to find your solutions

x - 4 = 0

x = 4

x + 2 = 0

x = -2

add solutions

since the two solutions are x = 4 and x = -2, add them together to get your final answer

4 + (-2) = 2
