seraphim [82]

Answer:

160 yards

Step-by-step explanation:

P=2l+2w

P=2(3w-8)+2(w)

432=2(3w-8)+2(w)

432=6w-16+2w

432=8w-16

432+16=8w

448=8w

w=448/8

w=56yards

l=3(56)-8

l=168-8=160yards

Use suitable identities to find the following products (x+4)(x+10)

Anestetic [448]

Answer:

$x^2 + 14x + 40$

Step-by-step explanation:

Here we gonna use the identity -

$(x+a)(x+b) = x^2+(a+b)x + ab$

So using the identity here,

$(x+4)(x+10) \\=> x^2 +(4+10)x+4*10\\=>x^2+14x+40$

A fountain is made up of two semicircles and a quarter circle. Find the perimeter of the fountain. Round to the nearest hundredt

Masja [62]

Answer:

75.40 feet

Step-by-step explanation:

For the two small semicircles, the circumference is $\frac{1}{2} 2\pi r$ , or just $\pi r$ . Since the radius is 1/2(16), or 8, the combined circumference of the two semicircles is 16 $\pi$ . Now, for the area of the quarter circle in the middle, we see that its radius is 16, and so its circumference is $\frac{1}{4} 2\pi r$ , or $\frac{1}{2} \pi 16$ = 8 $\pi$ . So, the perimeter of the fountain is 16 $\pi$ + 8 $\pi$ = 24 $\pi$ , or about 75.40 feet.
