7 0

Answer:

L = 20 cm, W = 10cm

Step-by-step explanation:

P=2L+2W

P=60,L=2W

60 = 2(2W)+2W

60=4W+2W

60=6W

W=10

plug in L=2W

L=2x10

L=20

What is the remainder to x^3+4x^2+x-6 divided by (x-1)
serg [7]

x^3=x^2\cdot x, and x^2(x-1)=x^3-x^2. This gives a remainder of

(x^3+4x^2+x-6)-(x^3-x^2)=5x^2+x-6

5x^2=5x\cdot x, and 5x(x-1)=5x^2-5x. This gives a new remainder of

(5x^2+x-6)-(5x^2-5x)=6x-6

6x=6\cdot x, and 6(x-1)=6x-6. This gives a new remainder of

(6x-6)-(6x-6)=0

and so there is no remainder.

###

Quicker method: Use the polynomial remainder theorem, which says the remainder upon dividing a polynomial p(x) by x-c is p(c). Here we have

p(x)=x^3+4x^2+x-6

c=1\implies p(c)=1+4+1-6=0

How do you solve for a missing measure on a triangle
Amanda [17]

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
