Do both variables. 

Here, we have 3 + √16-√21.

The square root of 16 is 4. (3 + 4 - √21)

Simplify. 7 - √21.

Square root of 21 is 4.5

7 - 4.5 = 2.4

Round. 2

Joe is the proud owner of Joe's Old Time BBQ Pit. He sells two types of BBQ sauce - Hot N' Spicy and Mild Mannered. Each gallon
oksano4ka [1.4K]

Answer:

P=$254

Step-by-step explanation:

let Hot N' Spicy be x

and Mild Mannered be y

  the objective function is

38x+35y=P

the constraints are

1. tomato sauce

2x+3y=18--------1

2. hot peppers

2x+y=10--------2

solving 1 and 2 we have

using substitution method

2x+y=10--------2

y=10-2x

put y=10-2x in eqn 1

2x+3(10-2x)=18

2x+30-6x=18

2x-6x=18-30

-4x=-12

x=12/4

x=3

put x=3 in eqn 2 we have

2(3)+y=10

6+y=10

y=10-6

y=4

He should make 3 gallons of Hot N' Spicy

and 4 gallons Mild Mannered

38(3)+35(4)=P

114+140=P

254=P

P=$254

Is a square a rectangle
hram777 [196]

Answer:

Yes

Step-by-step explanation:

Hi there,

Yes, the definition of a rectangle is "a plane figure with four straight sides and four right angles." A square has all of these, so by definition, a square is a rectangle.

But be careful! A square IS a rectangle but a rectangle IS NOT a square!

Hope this helps! Stay safe!
