Answered it step by step with this picture, hope this helped you! Basically all triangles add up to 180 degrees so you add the two sides, subtract the combination of the sides by 180 and then divide by 4x to get to the answer. Makes a lot more sense on img

Tariku was in second grade she read 6 book during each month of the year. She was in third grade she read 8 books during each mo
maks197457 [2]

Answer:

See below

Step-by-step explanation:

Tariku in second grade read 6 books each month during the year. This is equal to 6(12) = 72.

Tariku in third grade read 8 books each month during the year. This is equal to 8(12) = 96.

You can find the total amount with any of the below equations:

  • 6(12) + 8(12)
  • 12(6+8)
  • 12(14)

For a total number of months x the equations would be the same except with x instead of 12.

  • 6x+8x
  • x(6+8)
  • 14x

Someone please help me with problem #7 !!!
ser-zykov [4K]

Answer: b and d

Step-by-step explanation:

Since the roots are x=2 and x=6, we can write the equation as

f(x)=a(x-2)(x-6)

Substituting in the coordinates of the vertex,

-4=a(4-2)(4-6)\\\\-4=-4a\\\\a=1

So, the equation is f(x)=(x-2)(x-6)

On expanding, we get f(x)=x^2 - 8x+12
