Equilateral triangle because all three sides are equal.So all three internal angles are also congruent to each other and are each 60 degrees

7x - 3 = 60
7x = 63
x = 9

if you need to find for y
11y + 5 = 60
11y = 55
y = 5

2. You are trying to determine which box of Honey Nut Cheerios to buy, The Family Size box weighs

Katyanochek1 [597]

Answer:

Mega Size

Step-by-step explanation:

Given

Family Size

$Weight = 19.5\ oz$

$Cost = \$3.64$

Mega Size

$Weight = 29.4\ oz$

$Cost = \$4.98$

Required

Determine which has a better value

First, we calculate the unit rate of both.

$Unit\ Rate = \frac{Cost}{Weight}$

For the family size:

$Unit\ Rate = \frac{\$3.64}{19.5\ 0z}$

$Unit\ Rate = \$0.187\ per\ 0z$

For the mega size:

$Unit\ Rate = \frac{\$4.98}{29.4\ 0z}$

$Unit\ Rate = \$0.169\ per\ 0z}$

By comparing the unit rates, the mega size has a better value because it costs cheaper per unit rate

(c+d)^2+11(c+d)+30 Factor completely.

tatyana61 [14]

Answer:

firstable give c+b a polynomial value like x

so its will be x^2+11x+30

after the we have to factor it

30=6×5

and 11=6+5

so its will become

(x+6)×(x+5)=x^2+11x+30

x=c+d

(c+d+6)×(c+d+5)=(c+d)^2+11(c+d)+30

have a great day
