Answer:
Step-by-step explanation:
I assume that you need simplification of the given expression.
The given expression is:
Using distributive property and multiplying 2 inside the parenthesis and 1 inside the other parenthesis. This gives,
Therefore, is equal to:
Now, combining like terms using the commutative property of addition, we get:
Therefore, the simplified form is 
This one.
The doubly-shaded area is the solution set. The dashed line is not included.
The answer is A. one of the zeros is x = -1
<u>Answer:</u>
<h2>
ST = 44.54 ft</h2>
<u>Explanation:</u>
given:
∠T=90° , ∠R=39° and TR = 55 ft
ST = 55×tan(39)
ST = 55×0.80..
ST = 44.54 ft
Answer:
Step-by-step explanation:
A rectangle is shown with length x plus 10 and width 2 x plus 5.
so the rectangle area = length * width
= (x + 10) * (2x + 5)
an unshaded square with length x plus 1 and width x plus 1
so the unshaded square area = (x + 1) * (x + 1)
the shaded area = rectangle area - square area
= (x + 10) * (2x + 5) - (x + 1) * (x + 1)
= (2x^2 + 20x + 5x + 50) - (x^2 + x + x + 1)
= x^2 + 23x + 49
