Which addition expression is equal to 4 times one-fifth? One-ninth plus one-ninth plus one-ninth plus one-ninth
One-fifth plus one-fifth plus one-fifth plus one-fifth
Four-ninths plus four-ninths plus four-ninths plus four-ninths
Four-fifths plus four-fifths plus four-fifths plus four-fifths

One-fifth plus one-fifth plus one-fifth plus one-fifth

Step-by-step explanation:

1/5 + 1/5 + 1/5 + 1/5 = 4/5 = 4 x 1/5

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
