Question

Escreva o polinômio reduzido que represente perímetro de cada figura. Urgente !!

Answer 1

a) A1 = b x h
.....A1 = 5x^2 . (4x^2+x^2)
.....A1 = 5x^2 . 5x^2
....A1 = 25x4

....A2 = b x h
....A2 = 2x^2 . 4x^2
....A2 = 8x^4


....A3 = b x h
....A3 = 2x^2 . 4x^2
....A3 = 8x^2

At = A1 + A2 + A3
At = 25x^4 + 8x^4 + 8x^4
At = 33x^4 + 8x^4
At = 41x^4

b)A1 = b x h
....A1 = 4y^5 . y^5
....A1 = 4y^10

.....A2 = L^2
.....A2 = ( y^5 )^2
.....A2 = y^10

......A3 = b x h
......A3 = 4y^5 . y^5
......A3 = 4y^10

At = A1 + A2 + A3
At = 4y^10 + y^10 + 4y^10
At = 5y^10 + 4y^10
At = 9y^10

c) A1 = b x h
....A1 = z . 1/4z
....A1 = 1/4 z^2

....A2 = b x h
....A2 = 3/4z . 1/2z
....A2 = 2z . 3z/8
....A2 = 6z^2/8

At = A1 + A2
At = 1/4z^2 +6z^2/8.... m.m.c(4,8)=8
At = 2z^2 + 6z^2/8
At = 8z^2/8
At = z^2
