Determine the value of K that would make this expression a perfect square

Mumz [18]

Answer: k=9/4

Step-by-step explanation: We can do this by finding a number that adds up to 3 when multiplied by 2. The best way to do this is to use ((b^2)/4) which can usually find you the number for a perfect square based on b, which we have. So, 3^2 / 4 =9/4, meaning k=9/4. We can check:

>x^2 +3x +9/4

> (x+3/2)(x+3/2)

Perfect square.

Tony’s Electronics is marking down the price of a TV 23% from the original price of $175. Which expression can be used to find t

Arlecino [84]

Answer:

The sale price is $\$134.75$

The expression is $\$175(0.77)$

Step-by-step explanation:

we know that

The sale price is equal to subtract the discount price from the original price

The discount price is equal to multiply the original price by the percent discount in decimal form

Let

x ----> the sale price

y ---> discount price

$23\%=23/100=0.23$ ----> percent discount in decimal form

$y=\$175(0.23)=\$40.25$

$x=\$175-y$

substitute

$x=\$175-\$40.25=\$134.75$

therefore

the expression is

$175-0.23(175)\\175(1-0.23)\\175(0.77)$

Which expression represents the distance between the points (a, 0) and (0, 5) on a coordinate grid?

Mashcka [7]

$\displaystyle d= \sqrt{(x_1-x_0)^2+(y_1-y_0)^2}$ - d is distance, (x_1,y_1) and (x_0,y_0) two points on a coordinate grid.

In our case :
$(x_1,y_1)=(a,0)\\(x_0,y_0)=(0,5)$

$d= \sqrt{(a-0)^2+(0-5)^2} = \sqrt{a^2+25}$

For a right triangle that has legs a and b and hypotenuse c, find the length of the side not given here.

Sergio039 [100]

A^2 + b^2 = c^2
5^2 + 12^2 = c^2
c^2 = 25 + 144
c^2 = 169
c = 13cm
