To get the area of a triangle you use the equation A=1/2bh so 1/2 x 7 x 8= 28 square meters.
Open bracket
-69x+92+3x=56
Collect like term
-66x=-36
Divide both side by -66
x=6\11
Answer:
Step-by-step explanation:
The given graph is parabola graph with vertex at the point (2.0,24) and branches of the parabola go in a negative direction of y-axis.
As known parabola is symmetric about her <span>axis of symmetry and in this case the symmetry axis has equation t=2.0 (vertical line). Thus, the height of the javelin above the ground is symmetric about the line t=2.0.
</span><span>
</span><span>From the graph you can see that the first time when javelin is 20 feet above the ground is when t=1.0 and the second time is t=3.0 (to determine this you should draw horizontal line through point (0,20) and consider two points of intersection (1.0,20), (3.0,20) between parabola and horizontal line).

Answer:
The perimeter of Q' R' S' T' is 12.4 units. The shape QRST is undergoing a translation, so the size of the shape won't change, only the location. Therefore, the perimeter will stay the same.
