The diameter of a circle if five times the length of a recatngle. The length of a rectangle is three times the width of the rect
Leno4ka [110]

Answer:

706.5 ft²

Step-by-step explanation:

A. Width of the rectangle

The formula for the area of a rectangle is

A = lw

But, l = 3w, so,

A = (3w)w

= 3w² = 12

      w² = 4         Divided each side by 3

      w   = 2 ft     Took the square root of each side

B. Length of rectangle

l = 3w = 6 ft

C. Diameter of circle

d = 5l = 5 × 6 = 30 ft

D. Radius of circle

d = 2r

r = d/2     Divided each side by 2

r = 30/2 = 15 ft

E. Area of circle

A = πr² = 3.14 × 15² = 3.14 × 225 = 706.5 ft²

The area of the circle is 706.5 ft².

9- 4(2p+3) - 8p+7<br> how do i solve this ?
Sholpan [36]

Answer:

= -16p+4

Step-by-step explanation:

First we simplify:

9-4(2p+3)-8p+7

Then we distribute:

=9+(-4)(2p)+(-4)(3)+(-8p)+7\\=9+(-8p)+(-12)+(-8p)+7

Lastly, combine like terms:

=9+-8p+-12+-8p+7\\=(-8p+-8p)+(9+-12+7)\\=-16p+4

Hope this helps!

Have a good evening! :)

Complete the square to transform the quadratic equation into the form (x – p)2 = q. x2 - 12x - 5 = 7 A) (x - 36)2 = 9 B) (x - 6)
iren2701 [21]

x2 - 12x - 12 = 0

(x - 6)2 - 48 = 0

(x - 6)2 = 48

Hence, the answer is (B).
