Answer:

-170

Step-by-step explanation:

First, you would substitute 2 and 4 for a and b. 4 times 2 + 3(4 - 62) - 2 times 2 = ?

Then, do 4 times 2 (8), 3(4-62)=3(-58)

8 + -174 - 4 = -170

Sam rotated parallelogram ABCD 90° clockwise around the origin. If angle A is 130° and angle B is 50°, what is the degree measur

irakobra [83]

Answer-

The measurement of angle A' will be 130° .

Solution-

Transformations like - rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent.

It doesn't matter the order or how much degree of rotation has taken place, the final image will be congruent to the original image.

So, even after the rotation of 90° clockwise around the origin, the measurement of angle A will be 130° and so do all the rest of the angles.

Answer:

for a, look at my picture

b = 19.5 inches

Step-by-step explanation:

A is simple. thats my take on it, but other people coudl've drawn it differently

B is more difficult. I made triangle QRS like that so i can make a ratio.

My ratio:

QX:QY = QR:QS

8:12=13:QS

13*12 = 8*QS

156/8 = 19.5

therefore 19.5 inches

Nataly [62]

Answer:

How many general admission tickets were purchased? __136__

How many upper reserved tickets we purchased? _300_

Step-by-step explanation:

Let the number of general tickets = g.

Let the number of reserved tickets = r.

6.5g + 8r = 3284

g + r = 436

6.5g + 8r = 3284

(+) -8g + -8r = -3488

--------------------------------

-1.5g = -204

g = 136

g + r = 436

136 + r = 436

r = 300

Answer:

How many general admission tickets were purchased? __136__

How many upper reserved tickets we purchased? _300_

Sonja [21]

Answer:

p²-100q²

Step-by-step explanation:

p(p+10q)-10q(p+10q)

p·p+p(10q)-10q(p+10q)

p·p+p(10q)-10qp-10q(10q)

p·p+10pq-10pq-10q(10q)

p·p+0-10q(10q)

p·p-10q(10q)

p²-100q²
