Answer:
Step-by-step explanation:
If point A is between P and R, then;
PA+AR = PR
Given
PA=3x-4,
PR=21 meters,
AR=7 meters
Substitute
3x-4 +7 = 21
3x+3 = 21
3x = 21-3
3x =18
x =18/3
x = 6
Hence the value of x is 6m
Answer:
Length = 30 inches
Width = 24 inches
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Perimeter of a rectangle (P) = 2 width + 2 length
Since:
Length (L) = width (w) + 6
Replacing with the values given:
108 = 2w+2 (w+6)
Solving for w:
108 = 2w+2w+12
108-12 =2w+2w
96 =4w
96/4 =w
w= 24 in
Replacing w in the length formula:
L = w+6
L= 24+6 = 30in
