48 feet per second because
144/3=48
To solve the expression, we must know about an expression.
<h2>Expression</h2>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.
The solution of the expression is 2a.
<h3>Given to us</h3>
<h2>Solution</h2>
Multiplying both we get,
Taking 4 as common from the numerator,
Canceling (a+1) from both numerator and denominator,
Expanding further,
Canceling 2 and a,
= 2a
Hence, the solution of the expression is 2a.

The value of x is from negative infinity to negative 3/7 and 29 to positive infinity.
<h3>What is inequality?</h3>
Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The inequality equations are given below.
a) - 9x + 7 > 16 + 12x
b) 18 + 13x < 14x - 11
Then
a) - 9x + 7 > 16 + 12x
Solving for x, we have
21x < -9
x < -3/7
The value of x is less than the negative of 3/7.
b) 18 + 13x < 14x - 11
Solving for x, we have
x > 29
The value of x is greater than 29.

Answer:
462 words
Step-by-step explanation:
Maxine types :
294 words ⇒ 7 minutes
Let the known number of words be x.
So,
294 words ⇒ 7 minutes
x words ⇒ 11 minutes
Therefore,
294 ⇒ 7
x ⇒ 11
Now use cross multiplication and find the value of x.
7x = 294 × 11
7x = 3234
Now divide both sides by 7.
x = 462 words.
