PLS HELP ME EZ MATH GIVING 103 POINTS ALL MY POINTS PLS DUE NOW!!!

Perimeter:

18+4x+12+5x

=30+9x

Part B:

30+9(2)

=30+18

=48

Part A: 30 + 9x

Part B: 48

Step-by-step explanation:

Part A:

18 + 5x + 4(x + 3)

Use distributive property

18 + 5x + 4x + 12

Combine like terms

30 + 9x

Part B:

x = 2

30 + 9(2)

Use PEMDAS

30 + 18

48

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

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
