Do exactly what you did in the first part except with a constant letter from MATH
<span>If you cut the "whole" into 5 equal pieces, then 3/5ths would be 3 of those 5 pieces. so the answer is 3</span>
.if a is positive, the parabola opens up or to the right.
if a is negative, the parabola opens down or to the left
A parabola is a curved-forming shape in a graph that describes many important figures like the relationship, the focus and the magnitude of the variables involved.
Answer:
x = 6 cm
Step-by-step explanation:
The area is the product of length (x +2) and width (2x -5). It is 56 cm², so for all dimensions in cm, we can write ...
(x +2)(2x -5) = 56
2x² -x -66 = 0 . . . . . subtract 56 to put into standard form
(x -6)(2x +11) = 0 . . . . factor
Solutions to the equation are values of x that make the factors zero:
x = 6, x = -11/2
The negative solution is extraneous, so the solution of interest is ...
x = 6 cm
