Answer is x=3 cuz x^2-7x-18=0, so you would Cancel out the -18 to make it a positive 18th then bring the positive 18 over to the zero and then add 18 to 0 obviously it’s 18 and then you figure out the X to the second power minus 7X which is just 6X because x to the 2 power is x then you subtract seven eggs from X which is 6X so than6X equals 18 and then divide 18 by 6 which is three so x=3

Evaluate each logarithm. Do not use a calculator. Log (125)(1/25)
svetlana [45]

Answer:

-2/3

Step-by-step explanation:

Log125(1/25)=x

Raise each side to the base of 125

125^Log125(1/25)=125^x

1/25 = 125^x

Rewrite 25 as a power of 5  and 125 as a power of 5

1 / 5^2 = 5^3^x

The if power is in the denominator, we can bring it to the numerator by making it negative

5^-2 = 5^3^x

We know that a^b^c = a^(b*c)

5^-2 = 5^(3*x)

Since the bases are the same, the exponents are the same

-2 = 3x

Divide by 3

-2/3 = 3x/3

-2/3 =x

A circle has a diameter of 26 units. What is the area of the circle to the nearest hundredth of a square unit
Hitman42 [59]
To find the area of the circle, you will use the formula for finding area of any circle.

The radius is half the diameter.

A = pi x r^2
3.14 x 13^2
A = 530.66 square units

The area is 530.66 square units.
