Solve for x. enter your answer in interval notation using grouping symbols. x^2+15x<-36
Oliga [24]
X²+15x+36<0

at first solve quadratic equation

D=b²-4ac= 225-4*1*36= 81

x=(-b+/-√D)/2a
x=(-15+/-√81)/2= (-15+/-9)/2
x1=(-15-9)/2=-12
x2=(-15+9)/2=-3

we can write x²+15x+36<0 as (x+12)(x+3)<0

(x+12)(x+3)<0 can be 2 cases, because for product to be negative one factor should be negative , and second factor should be positive
 1 case)      x+12<0, and x+3>0,                                            
                       x<-12, and x>-3
(-∞, -12) and(-3,∞) gives empty set

or second case)  x+12>0 and x+3<0
x>-12 and x<-3
(-12,∞) and (-∞,-3)  they are crossing , so (-12, -3)  is a solution of this inequality

Plot of land between two roads are laid out according to the boundaries shown. The boundaries between the two roads are parallel
FinnZ [79.3K]
Given: 
                Cheshire Road           Shelby Road
Plot 1           40 yards                       48 yards
Plot 3                x                                56 yards


To solve for x, we get the ratio and proportion of both plots.

40/48 = x/56

Do cross multiplication.

40 * 56 = 48 * x
2,240 = 48x
2,240/48 = 48x/48
46.67 = x

Plot 3 of Chesire Road measures 46.67 or 46 2/3 yards.  Choice A.

Find the area of the following polygon:
Masja [62]

Given:

ABCD is a quadrilateral

AC = 12, DE = 4 and FB = 5

To find:

The area of the polygon.

Solution:

AC bisects the quadrilateral into two triangles.

Area of triangle:

$A=\frac{1}{2}\times\text{base}\times\text{height}

<u>Area of triangle DAC:</u>

$A=\frac{1}{2}\times AC \times DE

$A=\frac{1}{2}\times 12 \times 4

A=24

Area of triangle DAC = 24 square units.

<u>Area of triangle BAC:</u>

$A=\frac{1}{2}\times AC \times FB

$A=\frac{1}{2}\times 12 \times 5

A=30

Area of triangle BAC = 30 square units.

Area of polygon = Area of triangle DAC + Area of triangle BAC

                           = 24 square units + 30 square units

                           = 54 square units

The area of the polygon is 54 square units.
