A garden in the shape of a trapezoid has an area of 44.4 square

Leviafan [203]

Answer:

37 meters

Step-by-step explanation:

The equation for the area of a trapezoid is $A=\frac{a+b}{2} +h$ .

Here, $a = 4.3$ , $b=10.5$ , and $h$ is unknown.

$44.4=\frac{4.3+10.5}{2} +h$

$44.4=\frac{14.8}{2} +h$

$44.4=7.4 +h$

$37 = h$

The height of the trapezoid is the width of the garden, so the garden is 37 meters wide.

If H= 2f over m+1, solve the equation for f

Viefleur [7K]

H = 2f / (m+1)
[multiply by (m+1)]
h(m+1) = 2f
[divide by 2]
f = (h (m + 1)) / 2

3b / (b+2) = 12 / (b+2)
[multiply by (b+2)]
3b = 12
[divide by 3]
b = 4

3 / (6x + 1) / 2 = 8 / (x + 4) / 3
[multiply both denominators to mike one denominator]
3 / 8(6x+1) = 8 / 3(x+4)
[expand brackets]
3 / (48x + 8) = 8 / (3x + 12)
[multiply by (48x + 8)]
3 = 8(48x + 8) / (3x+12)
[multiply by (3x+12)]
3(3x +12) = 4(48x + 8)
[simplify]
9x + 36 = 192x + 32
173x = 4
x = 4 / 173
