The sum of integers p and q is modeled on a number line, where |p| < |q|. In each box write p,q, or p + q. Then write an addition equation

Answer:
Length = 2x+y cm and since it's a rectangle,
2x+y=3x-y ---------------- (i)
width = 2x-3 cm
It's perimeter,
2(2x+y+2x-3)=120 ---------------- (ii)
Solving both equations,
x = 14 cm
y = 7 cm
so length is, 2×14+7 = 35 cm
and width is, 2×14-3 = 25 cm
so area will be, 35×25 = 875 cm²

Answer:
x =
Step-by-step explanation:
Given,
Squaring on both L.H.S. and R.H.S.
By expanding L.H.S. we get x² + 49
By expanding R.H.S. we get x² + 10x + 25
x² + 49 = x² + 10x + 25
x² will be subtracted:
49 = 10x + 25
Variables are to be arranged:
10x = 49 - 25
10x = 24
x =
∴ x =
