Answer:

Step-by-step explanation:

We know that the shape is a triangle, and the first angle is 90 degrees.

since 1 and 2 are equal, and we know that the sum of the angles in a triangle is 180, we have:

180-90 = 90/2 = 45

(are you sure this is an 8th grade question? Because I'm 10 years old....)

Which expression can be used to approximate the expression below, for all positive numbers a, b, and x, where a Not-equals 1 and

defon

The expression that can be used to approximate the expression below is $log_a x = \frac{log_{b}a}{log_{b}x}$

Given the logarithmic function expressed as $log_a x$ , we need the log expression that is equivalent to the given expression.

To do this, we will write the logarithm as a quotient to the same base. Using the base of 10, the expression can be written as;

$log_a x = \frac{log_{10}a}{log_{10}x}$

This is similar to the option c where the base of "b" was used as $log_a x = \frac{log_{b}a}{log_{b}x}$

Evgesh-ka [11]

Answer:

1/4, 3/4

Step-by-step explanation:

First let's find how many marbles there are in total

6+10+8=24 marbles

Now we find the probability of drawing a blue marble

6/24=1/4 (There are 6 blue marbles)

The compliment is 3/4

Simplify the following expression completely using distribution and combining like terms

LiRa [457]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

Simplify ⇨ 19m + 14 - 3 (3m + 7)

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$\sf \: 19 m - 14 - 3 ( 3 m + 7 )$

Use the distributive property to multiply -3 by 3m+7.

$\sf \: 19m-14-9m-21$

Combine 19m and -9m to get 10m.

$\sf \: 10m-14-21$

Subtract 21 from -14 to get -35.

$\boxed{\boxed{\bf \: 10m-35 }}$
