5x^2= 2205
Divide both sides by 5
x^2=441
Find the square root of both sides
x= 21
Uhmmmm is there a picture of the problem i’m confused
<span>15 - 13(2x + 6) < 15 - 3(6x - 7)
15 - 26x - 78 < 15 - 18x + 21
-26x -63 < -18x + 36
-8x < 99
x > -99/8
or
x > - 12.375
</span>
(-3,7)(9,5)
midpoint formula : (x1 + x2)/2 , (y1 + y1)/2
(-3 + 9)/2 , (7 + 5)/2 = (6/2, 12/2) = (3,6) <==
15/100 × 215 = 3225/100
= 32.25
i am a mathematics teacher. if anything to ask please pm me
