I'm assuming you are asking 5x^2+7x = 6, and not 5*2 +7x = 6
We would use the quadratic formula to solve this.
5x^2+7x-6

(-7+-sqrt(7^2-4*5*-6))/2*5
(-7+-sqrt(49+120)/10
(-7+-sqrt(169)/10
(-7+-13)/10
-20/10=-2
6/10=3/5
So the answer is B) <span>x = –2 or x = 3/5</span>

A contemporary building has a window in the shape of a parallelogram with a base of 90 in and an adjacent side of 40 in. How man
BaLLatris [955]

260 inches of trim are needed to surround the​ window.

<h3 /><h3>What is the surface area?</h3>

The total land area of all the faces of a three-dimensional object is its surface area. When we wish to wrap something in real life, we employ the notion of surface areas of distinct things.

Actually, all we need is a trim that is the same size as our window and equal to the parallelogram's circumference, which is

The sum of the side is;

⇒Length of lower side + Length of the upper side

⇒ 90+90

⇒180 inches

The sum of adjacent sides;

Sum of adjacent sides  =  40+40

Sum of adjacent sides  = 80 inches

The length you should trim is needed to surround the​ window is found as;

⇒ 180 inches + 80 inches

⇒260 inches

Hence,260 inches of trim are needed to surround the​ window.

Marcus daims that in the expression 3x + 3y, the terms 3x and 3y are like terms because both are variable terms and both have th
kumpel [21]

Answer:

Step-by-step explanation:

3x and 3y are not "like terms," despite having the same coefficient.

Like terms have the same variable. For example, 3x and 2x are like terms, so

3x+2x = 5x

The company leased two manufacturing facilities. Lease A requires 20 annual lease payments of $200,000 beginning on January 1, 2
Fed [463]

Answer:

the present value of the lease obligation for lease A will be $1,702,712.74 while the present value of lease B will be $1,764,741.73

Step-by-step explanation:

the present value of annual lease payment will be determined by discounting the total amount to be received from lease payment over years.

for lease A  , Pv =   A \fracA{1 -(1+r)^{-n} }{r}

                         =   $200,000( 1 - (1+0.1)^{20}) / 0.1 =  $1,702,712.74

for lease B , Pv =   $220,000( 1 - (1+0.1)^-{17}) / 0.1  =  $1,764,741.73
