Answer:

Step-by-step explanation:

x^2 +12x-28=0

x^2+(14-2)x-28=0

x^2+14x-2x-28=0

X(X+14)-2(X+14)=0

(X+14)(X-2) is the factor of this quadratic equation.

Answer:

u=54

Step-by-step explanation:

VX is middle line of triangle, so

VX=ZY/2.....(1)

We know that

Zy=u

Vx=u-27

Put that in (1) we have:

u-27=u/2

2u-54=u

2u-u=54

u=54

Write an algebraic expression for the statement.The income earned at $ 10.91 per hour for w hours....

Alja [10]

This is a "rate of pay" problem. The amount earned is equal to the (rate of pay) times the (number of hours worked).

Let the income be represented by "i". Then the formula is i = ($10.91/hour)*w, where w is the number of hours worked and has the unit of measurement "hours."

URGENT! Can anyone explain how to solve this??

Alex

Check the picture below

the triangles are similar, the angles are congruents then

so... just add them up, and divide by 2, or set them as rational
