I need ONLY number 7 my teacher gave me this packet and i can’t figure that one out

(3x+6)^2

Step-by-step explanation:

the side of the inner square is 3x long

to have the wider square side we must add 3 two times, so 3x + 3 + 3 = 3x+6

to find the area we must square it (3x+6)^2

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

no solution

step-by-step explanation:

there is not enough information in the problem to solve.
