$f(g(x))=(2x^2+5)^2+2x^2+5+2\\
f(g(x))=4x^4+20x^2+25+2x^2+7\\
f(g(x))=4x^4+22x^2+32

Umnica [9.8K]

Answer:

62.8yd

Step-by-step explanation:

formula for circumference of a circle = 2 π r

The perimeter is 4 semi circles, so 2 full circles. The diameter is 10yd and the radius is half the diameter, so the radius is 5yd

working:

2 x π x 5 = 31.4yd

31.4 x 2 = 62.8yd

The area of a rectangle is 27 m^2 , and the length of the rectangle is 3 m less than twice the width. Find the dimensions of the

vagabundo [1.1K]

Let $L$ be the length of the rectangle and $W$ be the width. In the problem it is given that $L=2W-3$ . It is also given that the area $LW=27$ . Substituting in the length in terms of width, we have $W(2W-3)=27 \\ 2W^2-3W-27=0 \\ (2W-9)(W+3)=0$ . Using the zero product property, $2W-9=0 \text{ or } W+3=0$ . Solving these we get the width $W=4.5 \text{ or } -3$ . However, it doesn't make sense for the width to be negative, so the width must be $\boxed{4.5 \text{ m}}$ . From that we can tell the length $L=2(4.5)-3=\boxed{6 \text{ m}}$ .
