<span>15-h)*h=40
15h-h^2=40
h^2-15h+40=0
solve for h by quadratic formula:
a=1, b=-15, c=20
ans:
h=3.47 or 11.53 cm (height)
b=15-h=11.53 or 3.47 cm (base)</span>
5, 3, 7, 9 are all non-common factors
Answer:
x=y-6
Step-by-step explanation:
First, flip the equation.
x+6=y
Finally, add -6 to both sides.
x+6+−6=y+−6
x=y−6
Answer:
X=35
Step-by-step explanation:
X=35 because a straight line is 180 degrees. Take away 60 degrees and you're left with 3x + 15 = 120. Simplify to 3x=105, and then divide 3x by 3. Do the same to the other side. X will now equal 35. Hope this helps :)
