Answer:

180 - 16 - 126 = 38\\ 13x = 180 - 16  - 38\\ 3x = 126 \\ 3x = 126 \\ x =  \frac{126}{3}  = 42

X=42

Coresponding angles of similar triangle are congruent.

To find the missing angle of the triangle on the right you conplete the equation 180-126-16, which equals 38.

Since congruent angles of similar triangle are congruent, the leftmost angle on the triangle to the right is also 38.

After that you have to solve the equation:

180=16+38+3x.
180=54+3x
-54 -54
126=3x
/3 /3
42=x

Youre amazing!!! could you help me? 50 points!!! Write an expression that can be used to produce vector d from vector c, and exp
andrew-mc [135]

Answer:

Multiply vector c by the scalar -1/2.

Step-by-step explanation:

Look at vector c.

It has an x component of 4 and a y component of 4.

You can write vector c as a sum of its components using unit vectors in the x direction (i) and in the y direction (j).

c = 4i + 4j

Now look at vector d, and write it also as a sum of its x and y components.

d = -2i - 2j

Now ask yourself, what operation do I do to 4 to end up with -2?

One answer is to multiply 4 by -1/2.

d = (-1/2)c = (-1/2)(4i) + (-1/2)(4j) = -2i - 2j

That worked. By multiplying vector c by the scalar -1/2, you end up with vector d.

Apply the rules for order of operstions to simplify 2 + 3 - 4 (5 × 4)
Lerok [7]
Just use PEMDAS 
2+3-4 (5x4) 

Parenthesis
Exponents 
Multiplication
Division
Addition 
Subtraction    So first is Parenthesis 5x4=20 next will be Addition because there are no exponents 2+3= 5-4= 1 so now we go back to multiplication 20 x 1= 20 so 20 is your answer. 

Hope I helped out ^^

What is equivalent to <br> (3x+1)(4x-1)
valentinak56 [21]
(3x+1)(4x-1)

3x+4x=7x
1-1=0

So

(3x+1)(4x-1) = 7x

I hope this helped and was right, have a nice day
