Answer:

x= -6 twice

Step-by-step explanation:

x^2-3x-10/x^2+12x+36

By using undefined fraction we only take the denominator and equate it to 0

x^2+12x+36=0

x^2+6x+6x+36=0

(x^2+6x)+(6x+36)=0

x(x+6)+6(x+6)=0

(x+6)(x+6)=0

x+6=0 or x+6=0

x= -6 or x= -6

therefore x= -6 twice

Anna is looking for a new part-time job. They respond to a classified ad for
Veronika [31]

Answer: $2,393.42

Step-by-step explanation:

I suppose that the salary is yearly.

So in one year, 365 days, the net pay would be $62,400.

Now, "by-weekly" refers to two weeks or 14 days.

If she gets paid $62,400 in 365 days.

Then in 14 she gets paid.

N = (14/365)*$62,400 = $2,393.42

Answer:

g=56

Step-by-step explanation:

In similar shapes, corresponding sides are always in the same ratio.

For example,

if the sides in triangle 1 were a and b, and triangle 2 had side lengths c and d, c and a had the same ratios, and b and d had the same ratios

and triangle 1 was similar to triangle 2, the ratio between the sides of the triangles would be

a/c, which is also equal to b/d

What that means is that in this situation, 8/5=g/35.

8/5=g/35

Cross multiply.

(8)*(35)=g*(5)

280=5g

g=56
