Answer:
is their any way I can get some more info on this problem
Step-by-step explanation:
Well you have to factor first factoring gives you two value that you can multiply and get you a broken down version of that
you can do it two ways using the quadratic formula to factor or if you're really good at factoring just do it mentally (2x-5)(x+1)=0
for the mental way of doing the factors just set both 2x-5 equal to zero and x+1 = to zero
2x-5=0
2x=5
x= 5/2
x+1=0
x=-1
therefore the solutions are x = 5/2,-1
but if you want to learn how to do it mentally and with the quadratic function formula
let me know
The second answer is correct
Draw a line on the hole which forms a square. The square lengths are 3 inches because 12-9 equals 3. 3^2= 9 which is the area of that square below the rectangle. Draw another line to separate the big rectangle into two rectangles. The smaller of these two new rectangles dimensions are 4 by 7 in. 7x4= 28 ft as the area of the smaller rectangle. The dimensions are the larger rectangle are 4 by 9 inch. The area of the larger rectangle is 36 inches.
36+28+9=73 in^2 as the total area.
