Answer:
A=4
B=6
C=8
D=10
SA=248cm
Step-by-step explanation:
SA=bh+(s1+s2+s3)H
=6×8+(6+4+10)10
248cm
Answer:
y>2x-5
Step-by-step explanation:
-2y+4x<10
-2y<10-4x
divide by -2 to isolate the y
y>-5+2x
Since we are dividing by a negative the sign flips.
Our final answer is y>2x-5
For this case we have the following equation:
![\sqrt [4] {2x-8} + \sqrt [4] {2x + 8} = 0](https://tex.z-dn.net/?f=%5Csqrt%20%5B4%5D%20%7B2x-8%7D%20%2B%20%5Csqrt%20%5B4%5D%20%7B2x%20%2B%208%7D%20%3D%200)
If we subtract both sides of the equation
we have:
![\sqrt [4] {2x-8} = - \sqrt [4] {2x + 8}](https://tex.z-dn.net/?f=%5Csqrt%20%5B4%5D%20%7B2x-8%7D%20%3D%20-%20%5Csqrt%20%5B4%5D%20%7B2x%20%2B%208%7D)
To eliminate the radical we raise both sides of the equation to the fourth power:
![(\sqrt [4] {2x-8}) ^ 4 = (- \sqrt [4] {2x + 8}) ^ 4](https://tex.z-dn.net/?f=%28%5Csqrt%20%5B4%5D%20%7B2x-8%7D%29%20%5E%204%20%3D%20%28-%20%5Csqrt%20%5B4%5D%20%7B2x%20%2B%208%7D%29%20%5E%204)
Answer:
Option D
A + b = 35
b = 6a
a + 6a = 35
7a = 35
a = 5
b = 30
She scored 30 points in the second game
5/7 × 7/10 = 35 / 70 = 1/2
