Answer:
-4x^2+7x +6
Step-by-step explanation:
-7x + x^2 = - 3x^2 + 6
Subtract x^2 from each side
-7x + x^2-x^2 = - 3x^2-x^2 + 6
-7x =-4x^2 +6
Add 7x to each side
-7x+7x =-4x^2+7x +6
0= -4x^2+7x +6
The standard form is Ax^2 +Bx +C
Answer:
Step-by-step explanation:
Hello
A1 = (B + b) x h / 2
A1 = (8 + 2) x 5 / 2
A1 = 10 x 5 / 2
A1 = 25 cm^2
A2 = L x l
A2 = 6 x 8
A2 = 48 cm^2
A = A1 + A2
A = 25 + 48
A = 73 cm^2
Answer:
9/32 of the cookie was left for Stephanie to eat after lunch
Step-by-step explanation:
Anastasia’s mom baked a giant sugar cookie for her birthday.
On her birthday, ⅝ of the birthday cookie was eaten.
So, remaining cake =
The next day her brother ate ¼ of what remained.
Amount of cake eaten by her brother = 
So, remaining cake = 
Hence 9/32 of the cookie was left for Stephanie to eat after lunch
The equation for this problem can be written as 18x=162. X would represent the number of games bought. You do the inverse operation of multiplying by 18 to both sides and you get the answer as x=9. 9 is the number of games bought with 162 dollars.
