First find the value of h, or the height using the pythagorean theorem.

13^2=15^2+h^2
289=225+h^2
h^2=64
h=8

Then use the formula bh/2 to find area of the triangle.

10*8/2=40

Final answer: A

Need help with this asap <br> 5x+2+2x-10

Bess [88]

Answer:

7x - 8

Step-by-step explanation:

5x + 2 + 2x - 10

Rearrange terms:

5x + 2x - 10 + 2

Combine like terms (add 2x and 5x):

= 7x - 10 + 2

Combine like terms (add -10 and 2):

= 7x - 8 (This is the simplified form).

Which is an equation of the line that has a slope of 1/2 and passes through the point (2, 4)?

irina1246 [14]

Answer: $y = \frac{1}{2}x +3$ (Choice A)

Work Shown:

$y - y_1 = m(x - x_1)\\\\y - 4 = \frac{1}{2}(x - 2)\\\\y - 4 = \frac{1}{2}x + \frac{1}{2}(- 2)\\\\y - 4 = \frac{1}{2}x - 1\\\\y = \frac{1}{2}x - 1+4\\\\y = \frac{1}{2}x +3\\\\$

Explanation: I started with the point-slope form. Then I plugged in the given slope m = 1/2 and the point (x1,y1) = (2,4). Afterward I solved for y.

The answer is in slope-intercept form y = mx+b
