Trinomials in the form x2 + bx + c can often be factored as the product of two binomials. Remember that a binomial is simply a two-term polynomial. Let's start by reviewing what happens when two binomials, such as (x + 2) and (x + 5), are multiplied. Multiply (x + 2)(x + 5).

I need help with this problem. 2.9 × 10 ^11 - 3.7 × 10^13

lidiya [134]

$2.9\times10^{11}-3.7\times10^{13}=2.9\times10^{11}-3.7\times10^2\times10^{11}\\\\=10^{11}\times(2.9-3.7\times10^2)=10^{11}\times(2.9-3.7\times100)\\\\=10^{11}\times(2.9-370)=-367.1\times10^{11}=-3.671\times10^{13}$

which choice could be the equation of a line perpendicular to the line represented by this equation? y=2/5x=2 answers choice A(

ratelena [41]

The slope in y = mx + b form will be in the m position (the number before the x)
y = 2/5x ? 2..here the slope is 2/5.....a perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign.
2/5.....flip it....5/2...change the sign...-5/2...so we need a slope of -5/2.

answer C......y = -5/2x + (-3)
