Answer:
I honeslty dont know I just need points to answer a question
Step-by-step explanation:
hope you find the answer youre looking for!
8x^2 -3 = 2
add 3 to each side
8x^2 = 5
divide by 8
x^2 =5/8
take the square root of each side
x = +- sqrt (5/8)
Jana could have bought any number greater than 3.5 because 3.5 is the middle of 3-4. If the amount of trail mix is closer to 4 pounds, the pounds she could have bought must be greater than 3.5 but less than 4 pounds.
You have the area of the squares
100 in^2
area of a square = l*w
so length and width of the square both equal 10in
there are 4 squares going across the semi circle so...
diameter of semicircle is 10+10+10+10 =40in and radius is 20in
to find area of semicircle the formula is 1/2 pi r^2
so plug in the numbers 1/2(3.14) (20)^2 = 628 in ^2
now add that to area of big square part of window
40 inches length * 40 inches width = 1600in^2 (or you can just add them all up )
add up the areas now 1600+628= 2228 in^2
i think that is right
Answer:
Step-by-step explanation:
<u>Area of the regular polygon:</u>
- A = Pa, where P- perimeter, a- apothem
a. <u>Side length is:</u>
- s/2 = √13²-12² = √25 = 5
- s = 10 units
<u>Perimeter is:</u>
b. <u>Area is:</u>
