Answer:
1. It means that m equals 7.5
2. It means 4.5 plus s equals m
3. It means n times s equals 6
4. It means m plus n times s equals t

WY = a = 4
ZY = b = 3
As WYZ is forming a right angle triangle, therefore, we can use pythagorean theorem to find the value of c
a2+b2=c2 (4)2+(3)2=C2 16+9=C2 C2=25
Taking square root on both sides
√c2= √25 c=5
The value of c is 5 units.

Answer:
y = 3/4x + 2
Step-by-step explanation:
If we take the given points to be (0, 2) and (4, 5), then the slope is ...
m = (y2 -y1)/(x2 -x1) = (5 -2)/(4 -0) = 3/4
The y-intercept is given by the point (0, 2). So, the equation is ...
y = mx + b . . . . . . line of slope m with y-intercept b
y = 3/4x + 2
P left triangle = (2x+8) + (2x+7) + 2x
combine like terms
P left =6x+15
P right triangle = 2x+ 2x+ (3x+7)
combine like terms
7x+7
since the perimeters of the triangles are equal, set them equal
6x+15 = 7x+7
subtract 6x from each side
15 =x+7
subtract 7 from each side
8 =x
AB = 2x+8 = 2*8 +8 = 16+8 = 24
BC =2x+7 = 2*8+7 = 16+7 = 23
CA = 2x =2*8 = 16
PQ = 2x = 16
QR = 2x = 16
PR = 3x+7 = 3*8+7 = 24+7 = 31
