Which expression is equivalent to (x2 - 2x)(3x2 + 4x - 7)?

answer: equivalent expression is 3x^4-2x^3-15x^2+14x

step-by-step explanation:

equivalent expression we find product of given expressions.

consider,

(x^2-2x)(3x^2+4x-7)

=x^2(3x^2+4x-7)-2x(3x^2+4x-7)

=3x^4+4x^3-7x^2-6x^3-8x^2+14x

=3x^4+4x^3-6x^3-7x^2-8x^2+14x

=3x^4+(4-6)x^3-(7+8)x^2+14x

=3x^4-2x^3-15x^2+14x

answer: x

step-by-step explanation:

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
