Area of a triangle=bh/2
45=9(?)/2
45=9(10)/2
Therefore, h=10

Answer:

10 cm

Step-by-step explanation:

The area of a triangle

A = 1/2 bh

We know the area and the base

45 = 1/2 * 9*h

45 = 9/2h

Multiply each side by 2/9 to isolate h

45*2/9 = 2/9*9/2h

10 = h

Perform the indicated operation.(3/a+2) + (4/a-5)

kipiarov [429]

Answer:

$\frac{7(a-1)}{(a+2)(a-5)}$

Step-by-step explanation:

To solve this operation we need to find the common multiple of both denominators and solve for a.

$\frac{3}{a+2} + \frac{4}{a-5} =\frac{3(a-5)+4(a+2)}{(a+2)(a-5)} =\frac{3a-15+4a+8}{(a+2)(a-5)} =\frac{7a-7}{(a+2)(a-5)} =\frac{7(a-1)}{(a+2)(a-5)}$

Thus, the solution is 7(a -1) / (a+2)(a-5)
