This is a problem that could be solved with proportions. Here's how to set it up.
210mi./9 gallons =413mi./x gallons
Then, you would cross multiply 9x413 then divide that my 210. The result would be the X gallons. Good Luck ♡
Multiply the length 7 tiles by the width of 2 tiles to get the area of 14 tiles
Answer:
b
Step-by-step explanation:
Given:
The expression is

To find:
The equivalent expression.
Solution:
Distributive property of multiplication over addition is

Where, a, b and c are real numbers.
We have,

Using distributive property, we get


Therefore, the expression
is equivalent to the given expression.
To simplify x^2-3 =5x
You would first subtract 5x from both sides
X^3-5x-3
Next you would plug this into the quadratic equation:
X=5+/- the square root of: -5^2 -4(1)(-3)/2(1)
Then simplify,
5+/- the squareroot of 24 + 12 / 2
5+/- The squareroot of 36 /2
5+/- 6 / 2
Then solve if it’s an addition or subtract
5+6/2
X=11/2 or 5 1/2
5-6/2
X= -1/2
The answer is x=-1/2 or x=11/2
Hope this helps
