First subtract 30 from both sides so it is equal to 0
the quadratic formula is -b plus or minus sqrt of (b^2 - 4ac) all over 2a so
-10 plus or minus sqrt (100-25) all over 2
this is equivalent to

Step-by-step explanation:
5-3/-4--6 = 2/2 = 1
Hi
According to Pythagoras :
The square of hypotenuse is the sum if the square if the two other side
so : 7^2 + X^2 = 25^2
49 + X^2 = 625
X^2 = 625-49
X^2 = 576
this equation as two roots . As a triangle cannot have a negative side value, I will only take positive value
so X = V576 =24
Answer:
Just Transposition...
Step-by-step explanation:
12×7=84=d
92-49=43=e
28+57=85=f
96÷16=6=g
11×8=88=h
95+5-29=100-29=71=I
55-6+21=70=j
88+8÷4=96÷4=16=k
19+24-97=-97-43=54=m
-20+17+61=61+3=64=n
hope it helps
