Answer:
300 in²
Step-by-step explanation:
The TV screen is rectangular in shape.
Thus:
Length of the rectangular screen = 15 in.
Diagonal of the rectangular screen = 25 in.
To find the area of the rectangular screen, we need the length and the width of the screen.
Use pythagorean theorem to find the width as shown below:
, where:
a = width = ?
b = 15 in.
c = 25 in. (The hypotenuse/longest side)
Plug in the values into the equation
Subtract 225 from each side
Take the square root of both sides
width of the screen = 20 in.
Thus,
Area of the screen = length × width
= 15 × 20
Area = 300 in²
Step-by-step explanation:
a x^2/4
b -x^2/4+3
c 4x^2
d -x^2
Answer:
4 1/2
Step-by-step explanation:
2 1/3 pounds and 2 1/6 pounds
convert the 1/3 pounds into x/6 by multiplying both numerator and denominator by 2 which equals 2/6
Then add 2+2 which gives 4 and the 1/6 and 2/6 which is equal to 3/6 which simplifies into 1/2.
4 1/2
Answer:
Step-by-step explanation:
First rearrange all equations into this format:
that will result in:
then we'll multiply an equation with a number such that we have same numbers on both equations (with only different signs). So we can add them
Here you can see that we've multiplied the first equation with (-3) so that we have -9x on one equation and 9x on the other. Now when we add the two equations the 9x and -9x terms will cancel out (or eliminate)
now that we've found the value of y
we'll use this value in any of the two equations to get the value of x.
let's put y in the first equation:
