Answer:

a=5

Step-by-step explanation:

18=5a-2a+3

Combine like terms

18 = 3a +3

Subtract 3 from each side

18-3 = 3a+3-3

15 = 3a

Divide by 3

15/3 =3a/3

5 =a

Which equation can be used to find the unknown length, a, in this triangle?
Solnce55 [7]

Using the Pythagorean Theorem a^2 + b^2 = C^2

a and b are the sides and C is the Hypotenuse.

The picture you have sides of a and 15 and the hypotenuse is 17

The formula becomes a^2 + 15^2 = 17^2

Solveby factoring : <br> p2 + 8p + 12 = 0<br> (show steps please)
kramer

Answer:

(p + 6)(p + 2)

Step-by-step explanation:

I believe you meant  p^2 + 8p + 12 = 0, in which " ^ " indicates exponentiation.

Note that 12 = 2*6, and that these two factors, 2 and 6, add up to 8.  Thus,

p^2 + 8p + 12 = 0 = (p + 6)(p + 2)

Which expression gives the area of the triangle shown below?
kvasek [131]
The answer is d. The reason this is the answer is because to find the area of a triangle you will find half of the base times the height. The formula looks like this: A=1/2bh.

On this picture the base is the length of the bottom part of the triangle (c). It is the distance of the solid line only.

The height is represented as the straight line that is perpendicular to the base (forms a right/90 degree angle). X is the height of the triangle.

Therefore, 1/2cx is the answer.
