You want to solve for x first:
x+4-3=1 (combine 4 and -3)
x+1=1 (subtract 1 on both sides)
x=0
Answer:
32 aces
Step-by-step explanation:
4/20= x/160
once you set up this proportion you can cross multiple to get:
20x= 640
then just solve for x:
x= 32
What you can do is split one of the binomials and then apply the distributive property if f(x) = (x + 3)(x -2) split the 1st binomial f(x) = x(x -2) + 3(x -2) now apply the distributive property to get
f(x)=x2−2x+3x−6
which simplifies to
f(x)=x2+x−6
You have to use the Pythagorean theorem a squared plus b squared is c squared so 13 squared plus 18 squared equals c squared. 13x13=169 18x18=324 169+324=493 so c squared is 493 to get c you square root 493 which equals 22.2 so the diagonal, c, is 22.2 centimeters long
