Use the Distributive Property and simplify the expression. 6+4(3x – 2)+5

1 answer:

8 0

First, we need to use the distributive property to simplify the expression. So, that means we have to multiply the 4 by all of the integers and variables inside the parentheses.

If done correctly, your expression should be 6+12x-8+5

Next, we should combine all of the constant terms (just numbers without variables), also known as combining like terms.

If done correctly, your expression should be 12x+3.

This matches answer B. 12x+3

Please help me with this geometry question, Im pretty sure you need to use SAS congruence rule

Ierofanga [76]

Congruent triangles are two or more triangles with the same length of sides and measure of internal angles. Thus the required proof is as shown below:

From the given diagram, it can be observed that:

AB = AC (similar property of two lines)

AC = AE (similar property of two lines)

Also,

m<A is a common angle to ΔABC and ΔADE

So that it can be concluded that;

ΔABC ≅ ΔADE (Side-Angle-Side property)

Thus since ΔABC ≅ ΔADE are congruent, then;

BC = DE (corresponding sides of congruent triangles)

What is the domain of the square root function graphed below?

fiasKO [112]

Answer:

The domain is $[3,\infty)$ .

Step-by-step explanation:

Domain is the input to a function. The input to a function is marked along the x axis as the x values are the independent values and thus are in the domain of the function.

From the graph, the function starts at $x = 3$ when the point is (3,1) and then the graph of the moves towards infinity.

So, the domain of the function starts at 3 and move towards infinity.

Hence, the domain include the $x$ values between 3 to infinity including 3.

A wheel of radius 1.9 feet is moving forward at 12 feet per second. How fast is the wheel turning?

SOVA2 [1]

Find the circumference to see how much of the wheel is touhing the ground

c=2pir
c=2pi1.9
c=2.8pi

2.8pi=distance per 1 rotation
number of rotations per second times 2.8pi=12feet per second
dvide both sides by 2.8pi
number of rorations per second=12/2.8pi
number of roations per second=6/1.4pi
number of roations per second=3/0.7pi
number of roations per second=30/7pi
aprox
number of roations per second=1.364 rotations per second

Alice is playing a game in which she will roll 4 6-sided dice at the same time. She gets 5 points for each die that shows an eve

aleksley [76]

The expected value of x is 10.

It is given that the number of dice that are showing an even number is a binomial random variable with n = 4, and p = 1/2 (because half the faces on the die are even and half are odd).

The expected value of this random variable is n*p = 4*1/2 = 2.

The number of points is simply 5 times this random variable, and by the rules of expected value, E(C*Y) = C*E(Y), where C is a constant and Y is a random variable.

Thus E(X) = 5*2 = 10.
