Which values for a and b make the statement (a+6) (b-1)=0 true? a= -6,b=0 a=6,b=1 a= -6.b= -1 a=0,=b=0

The answers A, B, and C all work for this problem. The answer D is the only one that does not.

Step-by-step explanation:

When looking at two parenthesis being multiplied together and being equal to 0, we know that at least one of the parenthesis must be equal to 0 for it to be true. In A and C, the first parenthesis will be equal to 0 due to a = -6.

(a + 6)

(-6 + 6)

(0)

And in B, we can see that the second parenthesis would be equal to 0 due to b = 1

(b - 1)

(1 - 1)

(0)

Now we can try the D options, but will note that they do not work for either parenthesis.

(a + 6)(b - 1)

(0 + 6)(0 - 1)

(6)(-1)

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

the answer is 2/54
