SUBMIT

Answers

Answer: B. log(25) + log(18)

Step-by-step explanation:

Use the rule for the sum of logs: the log of a product is the sum of the logs, which means log(x) + log(y) = log(xy) if they have the same base.

Solution:

[tex] log(25 \times 18) \\ by \: \: \: using \: \: \: the \: \: \: following \: \: \: rule \: \: \: of \: \: \: logarithm \\ log(x \times y) = log(x) + log(y) \: \: \: \: we \: \: \: have \\ log(25) + log(18) [/tex]

Answer:

B. log (25) + log (18)

Write and solve an equation to find the value of x. PLSS HELP

Answers

Answer & Step-by-step explanation:

Vertical angles are congruent meaning that these two angles are going to have the same measurement. Since we know this, then we can set up an equation where one angle is equal to the other.

x + 10 = 55

Subtract 10 on both sides of the equation.

x = 45

So, the value of x is 45.

2/3a - 1/6 = 1/3

Answers

Answer:

a in this equation would be 3/4 because...

Step-by-step explanation:

2/3a−1/6=1/3

2/3a+−1/6=1/3

2/3a+−1/6+1/6=1/3+1/6

2/3a=1/2

Multiply both sides by 3/2.

(3/2)*(2/3a)=(3/2)*(1/2)

a=3/4

Answers

Answer: The theorem he used is the SAS (side-angle-side) theorem. The diagram actually depicts 2 sides and 1 angle, but the angle is not sandwiched by the sides, meaning it would be a SSA, not SAS.

Step-by-step explanation:

For Antonio to be correct, the angle would have to be between the two given side lengths, so it would have to be angle A or angle T.
