3 0

Answer:

(2u - 1)(5u + 1) =0

Step-by-step explanation:

The two subtractions in the equation means that it will be a plus and a minus and 10u would not get -3 nor -1

Answer:

$\large\boxed{S.A.=467\ in^2}$

Step-by-step explanation:

We have two triangles and three rectangles.

The formula of an area of a triangle:

$A_{triangle}=\dfrac{bh}{2}$

b - base

h - height

The formula of an area of a rectangle:

$A_{rectangle}=lw$

l - length

w - width

TRIANGLE:

b = 11 in, h = 7 in

$A_1=\dfrac{(11)(7)}{2}=\dfrac{77}{2}=37.5\ in^2$

RECTANGLE 1:

l = 11 in, w = 14 in

$A_2=(11)(14)=154\ in^2$

RECTANGLE 2:

l = 9 in, w = 14 in

$A_3=(9)(14)=126\ in^2$

RECTANGLE 3:

l = 8 in, w = 14 in

$A_4=(8)(14)=112\ in^2$

The Surface Area:

$S.A.=2A_1+A_2+A_3+A_4$

Substitute:

$S.A.=2(37.5)+154+126+112=467\ in^2$

The vertical asymptote is x = ?<br>y=a/x-h +k

gtnhenbr [62]

Answer:

x=a/(y-k)+h

Step-by-step explanation:

y-k=a/(x-h)

(y-k)(x-h)=a

xy-hy-kx+kh=a

xy-kx=a+hy-hk

x(y-k)=a+h(y-k)

x=a/(y-k)+h
