*The sum of the squares of the two adjacent sides of a parallelogram is 148 cm, one of its diagonals is 10 cm in length. Find the length of the other diagonal.* 1️⃣ 7 cm
2️⃣ 14 cm
3️⃣ 10 cm
4️⃣ 12 cm

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

if x = 1, then the answer is 3.5

ok thats very interesting
