Answer:
infinitely many solutions
Step-by-step explanation:
multiple -5 with x and -1 that's inside the parenthesis
-5 × (x-1) = 5-5x
-5x +5 = 5- 5x
add the like terms
-5x +5x = 5 -5 ➡ 0=0 we say there's infinite solutions because whatever value you write instead of x there will be an equation.
f(3) = 6
If f(1)=10, then f(1+1)=f(1)-2
f (2) = 10 - 2 = 8
Therefore f(3) = f(2) - 2 = 8 - 2 = 6
30
3x10=30
60
multiply length times width l x w
length is 10
width is 6
10 x 6 is 60
trapezoid, i got the last one wrong
