Answer:
a=16
Step-by-step explanation:
First of all you subtract both sides by 2 which makes 6-2=a/4 +2-2 which makes 4=a/4. then you multiply both sides by 4, 4x4=a/4 x 4 which makes a= 16 now you check this by putting a into the equation then going 16/4=4 then adding 2, 4+2= 6 then checking if it equals which it does
Would be amazing if you marked brainliest :)
Becaue the ones add up to 10 or more, they will regroup and put a 1 above the tens column to show the 10.
Here you are the
Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac (a, b, and c are the lengths of the 3 sides)
In words, the surface area of a rectangular prism is the area of the six rectangles that cover it. But we don't have to figure out all six because we know that the top and bottom are the same, the front and back are the same, and the left and right sides are the same.
The area of the top and bottom (side lengths a and c) = a*c. Since there are two of them, you get 2ac. The front and back have side lengths of b and c. The area of one of them is b*c, and there are two of them, so the surface area of those two is 2bc. The left and right side have side lengths of a and b, so the surface area of one of them is a*b. Again, there are two of them, so their combined surface area is 2ab.

Answer:
i'm not sure if this all correct
Step-by-step explanation:
part A you start at 8 from the first participant then you take away one from the last one. you add up all the numbers up to get the answer. 8+7+6+5+4+3+2+1=36.
part B the first part is 1x1x1x1x1x1x1x1=1. the second part is 8x7x6x5x4x3x2x1= 40,320. the third part is 1/40320
Answer:
Equation of tangent is
Step-by-step explanation:
Given:
Equation of curve, y = sec x
Passing through point =
We need to find Equation of tangent to the given curve and at the given point.
First we find the slope of the tangent by differentiating the given curve.
As we know that slope of the tangent, m =
So, consider
y = sec x
Now we find value of slope at given point,
put x = in above derivate
we get
Now using Slope point form, we have
Equation of tangent
Therefore, Equation of tangent is
