Since <A is congruent to <C , so triangle ABC is an isoceles triangle and side AB is congruent to BC.
AB = BC
Therefore, we can set up an equation as following:
10x - 7 = 2x + 33
10x - 7 - 2x = 2x + 33 -2x Subtracting 2x from each sides.
8x -7 = 33
8x - 7 + 7 = 33 + 7 Add 7 to each sides.
8x = 40
Divide each sides by 40.
So, x = 5
The length
the width
the height
so the amount of small cubes is
I believe that 4608 is the answer
good luck
Answer:
Option A Center (5,-4) radius 7
Step-by-step explanation:
x^2 +y^2 - 10x +8y - 8= 0
Center(-g,-f)
2gx = - 10x
g = - 5
2fy = 8y
f = 4
Center (5,-4)
Radius = square root of (g^2+f^2 - c)
r = square root of (5^2 + - 4^2 - (-8))
r = square root of (25+16+8)
r = square root of 49
r = 7
the sequence is 25/4(4/5)^x
plug in 10 for x to get your solution:
25/4(4/5)^10=4^9/5^8
