Answer:
D. 28.26 in²
Step-by-step explanation:
Area of a circle= πr²
r= 3
π= 3.14
A= (3.14)(3)²
A= 28.26 in²
Answer:
<em>The value of the expression for x=3 is 51</em>
Step-by-step explanation:
<u>Evaluating expressions</u>
To evaluate a given expression, we simply substitute the value of the variables and complete the operations.
The expression to evaluate is:
P=3(2+5x)
We will evaluate for x=3:
P=3(2+5*3)
The product must be done first:
P=3(2+15)=3*17=51
The value of the expression for x=3 is 51
Answer:

m is the slope...
Here,3/2 is the slope
Answer:
The measure of ∠D = (Q) = 28.81
Step-by-step explanation:
Tan(Q) = perpendicular/ base
In this case perpendicular is BC and base is DC
BC =25 DC = 45
Tan(Q) = BC/DC
Tan(Q) = 25/ 45
Tan(Q) = 5/ 9
(Q) = tan^ -1 (0.55)
(Q) = 28.81
