Answer:

Step-by-step explanation:

from the attached diagram, we can see that

LN = MP

3x + 1 = 8x -4

8x-3x = 1 + 4

5x = 5

x = 1

hence

LN = 3x+ 1 = 3(1) + 1 = 4

NM = 4x-1 = 4(1) - 1= 3

hence by Pythagorean formula,

diagonal NP = diagonal LM = √( 3² + 4²) = √25 = 5

Answer:

(b)

P = [4(4a + 3b]/(2a + b)

Step-by-step explanation:

P = 2L + 2W

P = [2(5a + 4b) + 2(3a + 2b)]/(2a + b)

P = [10a + 8b + 6a + 4b]/(2a + b)

P = [16a + 12b]/(2a + b)

P = [4(4a + 3b]/(2a + b)

Answer:

There are no solutions for the pair of equations.

The lines are parallel to each other

Step-by-step explanation:

Line Q has a slope of 1/2 and crosses the y axis at 3.

This mean at x=0, y=3

Using the equation of a straight line expression to find the slope
