Answer:
96 sq. m
Step-by-step explanation:
If the width is x, the length is x + 4 and since perimeter = 2 * (length + width), we can write:
40 = 2(x + x + 4)
40 = 2(2x + 4)
20 = 2x + 4
16 = 2x
x = 8 so x + 4 = 12, therefore the area is 8 * 12 = 96 square meters.

Solution:
X^2+11x+30
=X^2+(6+5)x+30
=X^2+6x+5x+30
=X(x+6)+5(x+6)
=(X+6)(x+5).
So,the answer is (x+6)(x+5).
Answer:
x = -1/10
Step-by-step explanation:
3 + 2/5x = -1
multiply through by 5x to make the equation linear
3 × 5x + 2/5x × 5x/1 = -1 × 5x
15x + 2 = -5x
collect like terms
15x + 5x = -2
20x/20 = -2/20
x = - 1/10
