Step-by-step explanation:
Area of rectangle
lw
So we have to factorise the expression
x²+13x+42
x²+6x+7x+42
x(x+6)+7(x+6)
(x+7)(x+6)
So
x+7-(x+6)
x+7-x-6

You must know that % is a number out of 100.
Therefore given 91/100 trusted DNA surveying, we know as a percentage this is 91% from the equation below:
(91/100)*100=91
We can conclude that 1%=1 person.
Although the difference is only 1 (91-90=1), the actual proportion of people who trust DNA testing is larger than the 90% by 1%.

Step-by-step explanation:
Gradient
= (y2-y1)/(x2-x1)
= (-9-(-5))(-2-(-4))
= (-4)(2)
= -8
