The length of a rectangle is 5cm more than it's width and the area is 55cm. find the length and perimeter of the rectangle

Inessa [10]

Answer:

L=10.326cm

P=31.30cm

Step-by-step explanation:

A=55=L*W

L=5+W

A = (5+W)(W) = 55

55=W^2 + 5W

0 = W^2 + 5W - 55

use quadratic formula

W = [-5 (+/-) sqrt(25-4(-55))]/2

W= 5.326 cm or W=-20.65, so W=5.326cm

L=5+5.326

=10.326cm

P=2W+2L

P=2(5.326) + 2(10.326)

=31.30 centimeters

Find the value of f(-3) and g(3) if f(x) = -6x + 3 and g(x) = 3x + 21r.

tekilochka [14]

Answer:

Part 1) $f(-3)=21$

Part 2) $g(3)=9+21r$

Step-by-step explanation:

Part 1) Find the value of f(-3)

we have

$f(x)=-6x+3$

we know that

f(-3) is the value of the function f(x) for x=-3

substitute the value of x=-3 in the function to find f(-3)

$f(-3)=-6(-3)+3$

$f(-3)=18+3$

$f(-3)=21$

Part 2) Find the value of g(3)

we have

$g(x)=3x+21r$

we know that

g(3) is the value of the function g(x) for x=3

substitute the value of x=3 in the function to find g(3)

$g(3)=3(3)+21r$

$g(3)=9+21r$
