Area of EBA = 60
(10 * AB)/2 = 60
AB = 12
Trapezoid Area = (12 + 28) /2 * height
Trapezoid Area = 20 *10
Trapezoid Area = 200 which is D
Answer:
<h2>y = 2.4x - 7.8</h2>
Step-by-step explanation:
The slope-intercept from of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The formula of a slope:
<em>(x₁, y₁), (x₂, y₂)</em><em> - ponts on a line</em>
<em />
We have two points (7, 9) and (2, -3).
Substitute:
Put the value of the slope and the coordinates of the point (7, 9) to the equation of a line:
<em>subtract 16.8 from both sides</em>
Finally we have:
Answer:
11 units
Step-by-step explanation:
HPO and DPI are similar triangles
HP/DP = PO/PI
HP/9 = 6/27
HP = 9×6/27
HP = 2
HD = HP + PD
HD = 2 + 9 = 11
Answer:
there is no solution
Step-by-step explanation:
Expand.
15x+35+2x=7x+10x-4515x+35+2x=7x+10x−45
2 Simplify 15x+35+2x15x+35+2x to 17x+3517x+35.
17x+35=7x+10x-4517x+35=7x+10x−45
3 Simplify 7x+10x-457x+10x−45 to 17x-4517x−45.
17x+35=17x-4517x+35=17x−45
4 Cancel 17x17x on both sides.
35=-4535=−45
5 Since 35=-4535=−45 is false, there is no solution.
No Solution
