Answer:
26) 5 : 11 (simplify it down by 2)
27) 19 : 17 (can't simplify it down)
28) 25 miles per hour (divide 75 by 3)
29) 15 : 24 (subtract 9 from 24 that would leave the amount of students left)
Answer:
-2
Step-by-step explanation:
Let's plug your functions f(x)=x^2-2x and g(x)=6x+4 into (f+g)(x)=0 and then solve your equation for x.
So (f+g)(x) means f(x)+g(x).
So (f+g)(x)=x^2+4x+4
Now we are solving (f+g)(x)=0 which means we are solve x^2+4x+4=0.
x^2+4x+4 is actually a perfect square and is equal to (x+2)^2.
So our equation is equivalent to solving (x+2)^2=0.
(x+2)^2=0 when x+2=0.
Subtracting 2 on both sides gives us x=-2.
Answer:
B: BC ≅EC
Step-by-step explanation:
You know that the two angles starting in C are congruent (they're opposite by vertex C).
Given that the B angle and the E angle are congruent, in order for the two triangles to be congruent by A(ngle)S(ide)A(ngle) you want the side inbetween to be congruent. That is BC and EC. Option B
Well both children has 110 marbles between them, and one child lost half and the other lost 20 so then it said they had an equal number so the other girl must had 20 so that makes 40 and 110-40= 80 so 80 is like the marbles that are left
Answer:
18 square units
Step-by-step explanation:
To find the area of a rectangle, we just need the length and height.
3 vertices of a rectangle are given, which is enough here to figure out the length (x-axis distance) and the height (y-axis distance).
From (0,0) origin to (3,0) would be 3 - 0 = 3 units in the x-axis. That is length:
Length = 3 units
Now, a point is given (0,6), that is in the y-axis. This is from origin. So, the height is:
6 - 0 = 6 units
Height = 6
Now, the area would be:
Area = Length * Height
Area = 3 * 6
Area = 18 square units
