What is the length of

Mathematics
1 answer:
saveliy_v [14]2 years ago
6 0

Answer:

17 units

Step-by-step explanation:

Because the triangle is isosceles, 2 of its sides are congruent; namely, the two sides that are opposite of the 2 congruent angles are contruent.

Because of the reason stated above, we can see that AC is congruent to BC, meaning that:

x+9=2x-8

-x      -x

9=x-8

+8  +8

17  = x

Notice that BC is equal to x, so 17 is our final answer.

alisha [4.7K]

Answer:

= 486 in²

Step-by-step explanation:

Linear scale factor = Image distance/object distance

Therefore; Linear scale factor = OL'/OL

                                                 = 54/ 12

                                                 = 9/2

Area scale factor is equivalent to the square of linear scale factor

Thus;

Area scale factor = (9/2)²

                             = 81/4

Hence; 81/4 = Area of larger rectangle/Area of smaller rectangle

Area of the smaller rectangle = 4 ×6 = 24 in²

Therefore;

Area of enlarged or larger pic = 81/4× 24

                                                  <u>= 486 in²</u>

Combining like terms ,algebra
telo118 [61]

Step-by-step explanation:

5x + 2 + 3x = 8x + 2

3 + 17x + 8 = 17x + 11

19 + 6x + 2x = 8x + 19

14x + 7 + 4 = 14x + 11

9x - 3 - 7x + 4 = 2x + 1

12x + 3x - 6 - 7f = 15x - 7f - 6

14x + 7 - 3x = 11x + 7

13z + 6u + 8x + 19 - u = 13z + 5u + 8x + 19

3z + 6 + 4z + 9 + 8u = 7z + 8u + 15

2x + 8z + 13u + 6z + 4u = 2x + 14z + 17u

14y + 13x + 12y + 19x + 4 = 26y + 32x + 4

5x + 18 - 13y + 12x + 8y = 17x - 5y + 18

21v + 8 - 12v - 7 + 3t - t = 9v + 2t + 1

3t + v - t + 7v = 2t + 8v

-1 + 18x -3y + x + 9y = 19x + 6y - 1

4x + 5y + 5x + 10y = 9x + 15y
