Let's say this number is a:
a*(a-9) = 90
a^2-9a-90 = 0
(a-15)(a+6) = 0
a = 15 or a = -6
Therefor a. would be the correct answer :)

Solve the equation of the function for n.

a(n) = 3n - 20

a = 3n - 20

a + 20 = 3n

(a + 20)/3 = n

n = (a + 20)/3

n(a) = (a + 20)/3

If (2x+10) and (3x+10) form a linear pair<br>find angles<br>.​
Alex_Xolod [135]
Linear pair angles are always supplementary.
So,
(2x+10) +(3x+10) = 180
5x+20 = 180
5x =180-20
5x=160
x= 160/5
x=32
Hence, the angles are 74 & 104

6th grade work please tell me the answer fast and don’t give me and incorrect one
anyanavicka [17]

Answer: 222cm

Step-by-step explanation:

To find the area of this composite shape you will have to split them into 2 shapes; a rectangle and a triangle.

To work out the area of the rectangle you have to do 15×12= 180

Then, to work out the area of the triangle, you use the formula base times height divided by 2.

7×12=84

84÷2=42

Then to work out the total area of both the rectangle and the triangle, you have to add the area of both.

180+42=222cm

Hope this helps :)
