How can I find the unknown side lengths when given the area or circumference of a figure?

ad-work [718]

Answer:

Set up the area/circumference equations using x as the unknown variable. Then, solve for that variable and apply the correct unit.

Step-by-step explanation:

For example,

Find the side length of a square with an area of 49 square centimeters.

Since $area=s^{2}$ , i can write $49=s^2\\then take the square root of each side to solve for s.\\s=\sqrt{49} \\s=7 centimeters$

Dimas [21]

Answer:

$2400 in A rated bond and $3000 in B rated bond.

Step-by-step explanation:

We have been given that Maria has recently retired and requested an extra $444.00 per year in income.

We can represent this information in an equation as:

$A+B=5400...(1)$

She has $5400 to invest in an A-rated bond that pays 10% per annum or a B-rated bond paying 6% per annum.

$0.10A+0.06B=444...(2)$

From equation (1), we will get:

$A=5400-B$

Substitute this value in equation (2):

$0.10(5400-B)+0.06B=444$

$540-0.10B+0.06B=444$

$540-0.04B=444$

$540-540-0.04B=444-540$

$-0.04B=-96$

$\frac{-0.04B}{-0.04}=\frac{-96}{-0.04}$

$A=2400$

Therefore, Maria should invest $2400 in A-rated bond.

Substitute $A=2400$ in equation (1):

$2400+B=5400$

$2400-2400+B=5400-2400$

$B=3,000$

Therefore, Maria should invest $3000 in B-rated bond.

Factor the polynomial:<br><br> a^4+2a^3-a-2

Black_prince [1.1K]

Answer:

(a-1) *(a^2 +a-1) (a+2)

Step-by-step explanation:

a^4+2a^3-a-2

Lets factor by grouping

a^4-a + 2a^3-2

Factor out an a from the first group and a 2 from the second group

a(a^3 -1) +2(a^3-1)

Factor out (a^3-1)

(a^3-1)(a+2)

We need to recognize that a^3-1 is the difference of cubes

(x^3-y^3) = (x-y) (x^2+xy+y^2)

Let x=a and y=1

(a-1) *(a^2 +a-1) (a+2)
