Hai !
6x+7+x^2+2x^2-3
6x+7+x^2+2x^2+-3
combine like terms
6x+7+x^2+2x^2+-3
(x^2+2x^2)+(6x)+(7+-3)
=3x^2+6x+4

Answer:

x = 13.8

Step-by-step explanation:

Given

See attachment for triangle

Required

Find x

To find y, we make use of the relationship between sides lengths 11 & x and angle 37

The relationship is:

cos(37) = \frac{11}{x}

i.e.

cos(\theta) = \frac{Adjacent}{Hypotenuse}

Make x the subject

x = \frac{11}{cos(37)}

x = \frac{11}{0.7986}

x = 13.7741

x = 13.8 -- approximated

What is the measure of one exterior angle of a regular hexagon?<br>a. 60<br>b.72<br>c. 90
Molodets [167]
To find the exterior angle measure we would use the following formula: 
\frac{360~degrees }{number ~of ~sides}
A regular hexagon has 6 sides so we divide: 
360/6 which equals 60 
So our final answer would be A. 60

Can someone help me?
Gnesinka [82]

Answer:

y =4(x-3)^2+2 => y=4x^2-24x+38

y=2(x-3)^2+4 => y=2x^2-12x+22

y=2(x+3)^2+4 => y= 2x^2+12x+22

Y= 4(x+3)^2+2 => y= 4x^2+24x+38
