A rectangle has a width of 5 meters and a length of 7 meters a similar rectangle has a width of 15 meters what is the length of

the similar rectangle?

Similar rectangles have or form similar ratios. Hence to solve this, you have to get the ratio of the measurements:
Let N be the length of the similar rectangle
  5/7 = 15/N
5(N) = 7(15) -> cross multiply
  5N = 105
 5N/5 = 105/5 -> divide both sides of the equation by 5
    N = 21
Therefore, 21 meters in the length of the similar rectangle
To check - 
5/7 = 15/21 (cross multiply)
105 = 105

Point K is on line segment JL. Given JK = 5x + 7, JL = 2x+8, and KL = 4,
kati45 [8]

Answer:

The numerical length of JL is 6 units

Step-by-step explanation:

Here, we want to determine the numerical length of JL

Mathematically;

JL = JK + KL

2x + 8 = 5x + 7 + 4

2x + 8 = 5x + 11

5x -2x = 8-11

3x = -3

x = -1

But JL = 2x + 8

JL = 2(-1) + 8 = -2 + 8 = 6

Dilation alters the length of the sides of a triangle but the angles remain the same 
So cos x will still be 8/17

Which of the following are solution to the inequality below -4w - 2 < -38
FromTheMoon [43]

Answer:

w > 9

Step-by-step explanation:

Solve the inequality by using inverse operations.

-4w - 2 < -38

-4w < -36

w > 9

Like solving equations, inequalities should be solved using inverse operations. However, unlike equations, when you divide or multiply by a negative the sign changes.
