As given Zahra has paper rectangles of different sizes.
Also, Every rectangle is 5 cm is longer than it's breadth.
So, if Length=L, then Breadth= L- 5
Or , if Breadth= B, then Length= B+5
or, if length is x and breadth is y ,then writing in terms of equation
→x=y+5
As you can see,there is not any proportional relationship between length and widths of these rectangles.
Equation
-4x + 16 = -116
solve for x
-4x + 16 = -116
subtract 16 to both sides
-4x + 16 - 16 = -116 - 16
simplify
-4x = -132
divide -4 to both sides
-4x/-4 = -132/-4
simplify
x = 33
answer: the number is 33
Ok so for number 5, AB is proportional to BC just like PQ is proportional to QR. AB = 9, BC = 15, PQ = 3, and QR = x. 9/15 = 3/x. Cross Multiply: This gives you - 9x = 45. Divide both sides by 9, and you get x = 5. QR = 5
Answer:
7
Step-by-step explanation: (dont trust me)
x^2 + (7)x +18
x(x + 4) + 3(x + 6)
I believe the answer is D
