What is (3m + 2) + (5x+8)=

5x + 3m + 10

Step-by-step explanation:

Remove parentheses:

3m+2+5x+8

Group like terms:

5x + 3m + 2 + 8

Add the numbers 2 + 8=10:

5x + 3m+ 10

3m+10+5x

Step-by-step explanation:

look at it without parenthesis might make it easier

3m+2+5x+8

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

the answer is 31.27mph
