Answer:
x^2 + 8x - 65 = 0.
Step-by-step explanation:
In order to solve the side of the enlarged area of 81 square inches, we use the equation in solving the area of a square. Area = side^2.
the increase in side will be x, so (4+x)^2 = 81, x^2 + 4x + 4x + 16 = 81
x^2 + 8x + 16 - 81 = 0
x^2 + 8x - 65 = 0.

Answer:
m = - 5
Step-by-step Explanation:
Product of two consecutive integer so this mean that x and y but y = x+1 than
x(x+1)=1332
x^2 +x -1332 =0 so bc. you get 36*37=1332 and 37x-36x=x so you can rewriting this quadratic factorized completlie
x^2 +x -1332 = 0
(x+37)(x-36)=0
x+37=0
x=-37 so the larger integer result that will be 37
Answer:
Step-by-step explanation:
take 69 degree as reference angle
using sin rule
sin 69=opposite/hypotenuse
0.93=7.2/x
x=7.2/0.93
x=7.74
x=7.7
