Can someone please do this i suck at math

Wittaler [7]

Answer:

Width = y + 7x

Step-by-step explanation:

Area of the rectangle = ${y}^{2} + 8xy + 7 {x}^{2}$

Length of the rectangle = $y + x$

Lets factorise ${y}^{2} + 8xy + 7 {x}^{2}$

$= > {y}^{2} + xy + 7xy + {x}^{2}$

$= > y(y + x) + 7x(y + x)$

$= > (y + 7x)(y + x)$

Now ,

Width = $\frac{Area}{Length} = \frac{(y + 7x)(y + x)}{(y + x)} = y + 7x$

Write the equation of a circle centered at the

Fudgin [204]

Answer:

$(x+4)^2+(y+6)^2=100$

Step-by-step explanation:

Given a circle centred at the point P(-4,-6) and passing through the point

R(2,2).

To find its equation, we follow these steps.

Step 1: Determine its radius, r using the distance formula

For point P(-4,-6) and R(2,2)

$\text{Distance Formula=}\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\text{Radius=}\sqrt{(2-(-4))^2+(2-(-6))^2} \\=\sqrt{(2+4))^2+(2+6)^2}\\=\sqrt{6^2+8^2}\\=\sqrt{100}\\Radius=10$

Step 2: Determine the equation

The general form of the equation of a circle passing through point (h,k) with a radius of r is given as: $(x-h)^2+(y-k)^2=r^2$

Centre,(h,k)=P(-4,-6)

r=10

Therefore, the equation of the circle is:

$(x-(-4))^2+(y-(-6))^2=10^2\\\\(x+4)^2+(y+6)^2=100$

Sami's bank account earns 4% simple interest per year. If Sami deposits $500, how much simple interest will she earn in one year

timurjin [86]

Answer:

$20 simple interest.

Step-by-step explanation:

The simple interest that Sami earns is 4% of her deposit since she is trying to find how much she will earn in one year (given that the interest rate is 4% per annum).

$\$500\times4\%=\$20$

∴ Sami earns $20 simple interest in one year.

Hope this helps :)

The sum of two numbers is 100, the difference between the two numbers is 26. What is the number that is less?

Zepler [3.9K]

The numbers that would be smaller would be the two with the difference of 26.
27-1=26 where as, if you were to use a 1 in each, 99+1= 100. Therefore 27 and 1 (28) is less than 99 and 1 (100).
