We know that
lateral area=3*[area of a equilateral triangle]
Applying the law of sines to calculate the area of a equilateral triangle
Area=(1/2)*a*b*sin C
a=4
b=4
C=60 degrees
area equilateral triangle=0.5*4*4*sin 60-----> 0.5*4*4*√3/2---> 4√3 units²
lateral area=3*[4√3]----> 12√3 units²

the answer is
12√3 units²

Which are correct representation of the inequality minus 32X -5 less than 52 minus X select two options
Murljashka [212]

Answer:

The value of X is more than equal to -1.83.

Step-by-step explanation:

We need to find the correct representation of the inequality 'minus 32X -5 less than 52 minus X'

LHS of the inequality will be : -32x-5

RHS of the inequality will be : (52-X)

So,

-32X-5\leq 52-X

Adding X both sides

-32X-5+X\leq 52-X+X\\\\-31X-5\leq 52

Adding 5 to both sides,

-31X-5+5\leq 52+5\\\\-31X\leq 57

Dividing both sides by -31.

X\geq \dfrac{-57}{31}\\\\X\geq  -1.83

So, the value of X is more than equal to -1.83.

The temperature at noon is 0°C. The temperature changes buy-3/2°C every hour for 4 hours. Write a expression to represent this s
aniked [119]

Answer:

So the temperature at 4:00 pm which is exactly 4 hours from 12 noon is -3/2°c

T = To + (-3/2°c)x

Where x is the fraction of 4 in hours

Step-by-step explanation:

Its a very simple Expression.

First we consider the first temperature at first time which is 0°c at 12 noon which I initial time, i.e t= 0.

For every four hour change , the temperature adds -3/2°c .

So the temperature at 4:00 pm which is exactly 4 hours from 12 noon is -3/2°c

The expression to know the temperature is

T = To + (-3/2°c)x

Where x is the fraction of 4 in hours

Using the distributive property simplify the expression<br> -2(5y + 6) + 3 - 5y
vivado [14]

Answer:

\Huge \boxed{-15y-9}

Step-by-step explanation:

To solve this problem, first you have to use the distributive property of \displaystyle a(b+c)=ab+ac.

First, expand.

\displaystyle -2(5y+6)

-2*5=-10

\displaystyle -2*6=-12

\displaystyle -10y-12

\displaystyle -10y-12+3-5y

Next, solve.

\displaystyle -10-12+3-5=\boxed{-15y-9}

In conclusion, the correct answer is -15y-9.
