Need help on this, need help now D:
baherus [9]

Answer:

\sqrt{34}

Step-by-step explanation:

Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(- 2, 5) and (x₂, y₂ ) = B(3, 8)

d = \sqrt{(3+2)^2+(8-5)^2}

   = \sqrt{5^2+3^2}

   = \sqrt{25+9}

   = \sqrt{34}

I’m horrible at geometry, help please?
Korvikt [17]

Answer:

Longest side = 13 inches

Step-by-step explanation:

Perimeter of triangle =  30 inches

x + 4x - 8 + 2x +3    =  30

x + 4x + 2x - 8 + 3 = 30

                   7x - 5 = 30

                          7x = 30 + 5

                          7x = 35

                            x = 35/7

         x = 5

Longest side is the hypotenuse.

Longest side = 2x + 3 = 2*5 + 3 = 10 + 3 = 13 inches

A grocer wants to make a 10-pound mixture of peanuts and cashews that he can sell for $4.75 per pound. If peanuts cost $4.00 per
vladimir2022 [97]
The grocer wants to make a 10 pound mixture 
p - pounds of peanuts
c - pounds of cashews
therefore the total pounds should be equal to 10 pounds 
p + c = 10 -----> 1)
the cost for ;
peanuts - 4.00 per pound * p pounds = 4p
cashews - 6.50 per pound * c pounds = 6.5c
the price of 10 pounds mixture = 4.75 per pound * 10 pounds = 47.5
4p+6.5c = 47.5 ---> 2)

to solve for p and c lets use simultaneous equations 
p + c = 10 -----> 1)
4p+6.5c = 47.5 ---> 2)
multiply 1st equation by 4
4p + 4c = 40 ---> 3)
subtract 3rd equation from the 2nd
2.5c = 7.5
c = 3
substituting c= 3 in 1st equation
p+c = 10
p+3 = 10
p = 7
therefore 3 pounds of cashews and 7 pounds of peanuts are needed to make the mixture
