You must use quadratic formula for each.
The term in front of the
is the "a" value in the quadratic formula. The term in front of the
is the "b" value. And the constant term (no x's) is the "c" value. Now you must simply substitute these values into the quadratic formula for each question.

Answer:
Potato price = $1.5 / pound ; Carrot price = $1.75 / pound
Step-by-step explanation:
Let price of carrot per pound = c
Let price of potatoes per pound = p
Given :
2c + 3p = 8 (eqtn A)
4c + 4p = 13 (eqtn B)
Multiplying eqtn A by 2 ;
4c + 6p = 16
4c = 16 - 6p (eqtn Y)
By eqtn B ;
4c = 13 - 4p (eqtn Z)
By eqtn Y & Z ;
16 - 6p = 13 - 4p
16 - 13 = - 4p + 6p
3 = 2p
p = 3 /2
p = 1.5 [Potato price]
Putting p value in eqtn A
2c + 3 (1.5) = 8
2c + 4.5 = 8
2c = 8 - 4.5
2c = 3.5
c = 3.5 / 2
c = 1.75 [Carrot Price]
The length of a side of a triangle must be less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides.
12 in. + 14 in. = 26 in.
14 in. - 12 in. = 2 in.
The third side must measure more than 2 inches and less than 26 inches, but we are told that the 14-inch side is the longest side of the triangle, so the third side must measure less than 14 inches. The largest whole-number length less than 14 inches is 13 inches.
Answer: It measures 13 inches.
Its the first one because if the circle is filled in than it is 2and more or the thing
9 because if you change 1 and 4/5 to an improper fraction and you’ll get 9/5. If you multiply 1/5 by 9 you’ll get 9/5.
