If a x b = 2a - 3b + ab, then 3 x 5 + 5 x 3 is equal to?
A. 20
B. 22
C. 24
D. 26

Answers

Answer:

B. 22

Step-by-step explanation:

3 * 5 + 5 * 3 = (2 * 3 - 3 * 5 + 3 * 5) + ( 2 * 5 - 3 * 3 + 5 * 3)

                   = (6 + 10 - 9 + 15) = 22.

Answer:

B. 22

Step-by-step explanation:

If the perimeter of a rectangular picture frame must be less that 200 in, and the width is 36 in. what must the height H of the frame be?

Answers

Answer:

w = width

h = height

2(w+h) < 200

w + h < 100

since w = 36, then

36 + h < 100

h < 100 - 36

h < 64

Step-by-step explanation:

The perimeter of the rectangular picture frame can be calculated by the equation,

                                 2h + 2w = P

where h and w are height and width , respectively. Substituting the known values and the condition for the inequality,

                                2h + 2(36 in) < 200

The inequality gives h as,

                                          h < 64

Thus, the answer is letter A.

what’s the perimeter of a rectangle with 6x+10 as it’s width and 4x+1 as it’s length

Answers

Answer:

the equation will be  2(6x+10+4x+1)

simplified to

12x+20+8x+2

simplified to

20x+22

The perimeter of the rectangle will be 20x+22

Thank you, Hope it helps

Answer: The length of both sides would be 12x+20 and the width of both sides would be 8x+2, so the perimeter of the rectangle would be 20x+22

hundreds digit and tens digit add to make 9

half of it is less than 100.

I suppose 180 can correctly fit into all above criterions

It is 3 digit number. 1+8 =9, 180/2 =90 which is less than 100.

Step-by-step explanation:

4x+11+2x-2 = 180 - 105

6x+9 = 75

6x = 66

x = 11

2(11)-2 = 22-2 = 20 degrees!

Answers

Answer:

The degree for all triangles is 180 so

The 55 angle is the same on both sides so

55+55=110

To find x we subtract 180-110 and that equals 70

The two operations are addition and subtraction

What is the relationship between the corresponding angle bisectors BD and XZ?

Answers

Answer:

XZ = 2.5 BD

Step-by-step explanation:

Comparing the two triangles,

[tex]\frac{BD}{BC}[/tex] = [tex]\frac{XZ}{XY}[/tex]

[tex]\frac{6}{8}[/tex] = [tex]\frac{XZ}{20}[/tex]

⇒ XZ = [tex]\frac{20*6}{8}[/tex]

         = 15

XZ = 15

So that,

BD:XZ = 6:15

           = 1:2.5

Therefore, the relationship between BD and XZ is XZ = 2.5 BD.
