Let x represent the width of the garden(s). Then the length of the second garden is (3x+3). The area is the product of length and width,
90 = x(3x+3)
30 = x(x+1)
At this point, you can recognize that 5 and 6 are factors of 30 that will satisfy this equation, or you can solve the quadratic
x² +x -30 = 0
(x +6)(x -5) = 0
x = 5 . . . . . . . the negative solution does not apply
The width of the garden is 5 m.
16a.) π
16b.) 
= 7 ÷ 15
Put (7 ÷ 15) in your calculater to get 0.4666667
That multiplied by 100 and rounded to the nearest whole percent is
47%
17a.) 24 + 16 + 14 = 54
17b.) 8 ÷ 27 = 0.296
0.296 × 100 = 29.6
Rounded to the nearest whole number is 27%
You would pick You would choose 6xy, or 67xy, unless that is with the 1/7,
and this is because the definition of a coefficient is "<span>a numerical or constant quantity placed before and multiplying the variable in an algebraic expression",
so both of these have variables.</span>
