7/3x+1/3x=3x+6/3+5/3x
8/3x-5/3x=3x+6/3
3/3x=3x+6/3
x=3x+6/3
x-3x=6/3
-2x=2
-x=2/2
-x=1
x=-1
Y ^(-2/3)^-6 = y^12/3 = y^4
x^(1/2)^ -6 = x^-3 = 1 x^3
so the answer is y^4 * 1 /x^3 = y^4 / x^3
A
Every number gets multiplied by 6...
So the answer is...
ANSWER = 64 = 1296
Answer:
1.8 cm
6.3 cm²
Step-by-step explanation:
AC⊥BC
BD=BC=x
- (x+5)²+x²=7²
- x²+10x+25+x²=49
- 2x²+10x- 24=0
- x²+5x-12=0
- x=1.8
BC= 1.8 cm
Area of ABC= 1/2*1.8*7= 6.3 cm²
About 5 books have been signed out, so they still have 4.
