Answer:
-2
Step-by-step explanation:
2(x-4)+3x-x² for x = 3
is : 2(3-4) +3(3)-3² = -2 ... answer : B
Answer:
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula.
The distance formula is:
Let (2,8) be x₁ and y₁ and let (7,7) be x₂ and y₂. Thus:
Simplify:
Square:
Add:
And that's our answer :)
The x value will be 109°. The straight line formed a 180° angle. Solving the equation yields the angle.
<h3>What are supplementary angles?</h3>
Supplementary angles are two angels whose sum is 180°. When a straight line intersects a line, two angles form on each of the sides of the considered straight line.
Those two-two angles are supplementary angles in two pairs. That is, if two supplementary angles are adjacent to each other, their exterior sides form a straight line.
The straight line formed a 180° angle. The resulting equation is as follows:
⇒x+42°+29°=180°
⇒x=109°
Hence, the value of the x will be 109°
The complete question is:
AB is a straight line.

I'm putting together assumptions as this isn't really clear to me, I apologize.
Answer: A.90 cm^2
Step-by-step explanation: A= a+b/2 h
A= 17.5+12.5/2 *6
A = 30/2*6
A= 15*6
A=90
