Step-by-step explanation:
5x=11-7
5X= 4
X=4/5
=0.8 Answer
121 is the area of the square
To multiply exponents with like bases, simply add the exponents...
3^-3 × 3^4 × 3 × 3^-5 =
add exponents across, remember just 3 means 3^1.
-3 + 4 + 1 + -5 = -3
answer is 3^-3
Answer:
x=-8 OR X=2
Step-by-step explanation:
X²+6X-6=10
X²+6X-16=0
X²+8X-2X-16
X(X+8)-2(X+8)
X+8=0 X-2=0
X=-8 OR X=2
Answer:
v=5.42m/s
Step-by-Step Explanation:
We can use conservation of energy to solve this
mgh=1/2mv^2
2gh=v^2
v=sqrt(2gh)
v=sqrt[2*9.8m/s^2*(6.5-5)]
v=5.42m/s
