We know that total surface area is the area of of the base + area of all the walls + area of the top
here we are working with a pyramid whose base is a square but the wall are four triangles
as triangles are connected on the top , there would be no top area ( as the top would be a point ( where all four triangles are being join )
so total area is = area of base + area of four walls ( triangles here )
Answer:
sqrt7/4
Step-by-step explanation:
sin is opposite/hypotenuse which means sqrt63/12 then sqrt63=3sqrt 7 and simplifies get (sqrt7)/4 Done!
<u>Answer:</u>
<u>Step-by-step explanation:</u>
-4x - 9y = -25
7(-4x - 9y = -25)
-28x - 63y = -175
<u>Now, let's substitute the value of y into the first equation.</u>
- => -7x - 2y = 25
- => -7x - 2(5) = 25
- => -7x - 10 = 25
- => -7x = 35
- => x = -5
<u>Now, let's check our answer to make sure our answer is correct.</u>
<u>Check:</u>
- -4x - 9y = -25
- => -4(-5) - 9(5) = -25
- => 20 - 45 = -25
- => -25 = -25
Hence, this is proved correct.
Hoped this helped.

The answer is 96.
The 3,a,b,& c cancel out because they equal 1.
Then your left with 48*2 which is 96.
48 * a * 3 * b * c * 2--------------------------3 * a * b * c
3/3 = 1 B/b = 1 C/c = 1
1 * 1 * 1 * 48 * 2 = 96
Answer:
Step-by-step explanation: 14+14 is 28 do this twice because you said 14x4
and that gets you another 28, add the two 28's together and you have 56
