Let the original length of the square be x cm.
(x+5) X (x-2) = 60
Or, x^2-2x+5x-10-60 = 0
Or, x^2+3x-70=0
Or, x^2+10x-7x-70=0
Or, x(x+10)-7(x+10)=0
Or, (x-7)(x+10)=0
Therefore, x=7 or x=-10 (rejected as the length cannot be negative)
Ans: Area of the square=l^2=7^2=49 square meters.
Answer:
Width = 9 cm, length = 14 cm
Step-by-step explanation:
Width = w; Length = L
2(W+L) = 46, W+L = 23, W= 23-L
W*L = 126, (23-L)*L = 126
W = 9, L = 14
Answer:
(-2, 1)
Step-by-step explanation:
The 4th point must be vertically above (-2, -4) and horizontally to the left of (3, 1).
Its coordinates are (-2, 1).
It is A (8y + 1)(y + 2) because if you multiply it out you get 8y^2 + 16y + 1y + 2 which is equal to 8y^2 + 17y + 2
