Answer:
28.8 cm
Step-by-step explanation:
Since a square's length is the same for all four sides, we have
7.2 + 7.2 + 7.2 + 7.2 or 7.2(4)
We should get 28.8 cm as our answer.
3(2x+2)=3x-15
mutiply the bracket by 3
(3)(2x)(3)(2)= 6x+6
6x+6= 3x-15
move 3x to the other side
sign changes from +3x to -3x
6x-3x+6= 3x-3x-15
6x-3x+6= -15
3x+6= -15
move +6 to the other side
sign changes from +6 to -6
3x+6-6= -15-6
3x= -21
divide by 3 for both sides
3x/3= -21/3
x= -7
Answer: x= -7
Answer:
The football is going to go over the goal post. It will clear the goal post by (16-10) 6 ft
Step-by-step explanation:
y = -0.03x^2 + 1.6x
Let x = 40
We need to determine if y> 10
y = -0.03(40)^2 + 1.6(40)
y = -48+64
y =16
Since 16>10
The football is going to go over the goal post. It will clear the goal post by (16-10) 6 ft
Answer:
-3
Step-by-step explanation:
The graph shows the straight line.
To find the value at x = 2, draw the vertical line passing through the point (2,0). This line intersect the graph at some point. Draw the horizontal line through this point of intersection. This line intersects y-axis at point (0,-3). This means that the coordinates of the point lying on the graph are (2,-3) so
f(2) = -3
