Find the zeros of the function <br> F(x)=x^2-5x+5

oee [108]

You would have to replace f(x) with zero and use quadratic formula

f(x)=x^2-5x+5
0=x^2-5x+5

=(-b+-√b^2-4ac)/2a
=(5+-√25-4(1)(5))/2
=(5+-√5)/2

x=(5+√5)/2 or x=(5-√5)/2

Both x values are completely applicable in the equation.

Hope I helped :)

What is x if the equation is, 4 - (2x-3) = 3?

user100 [1]

Answer:

x = 2

Step-by-step explanation:

4 - (2x-3) = 3

Distribute the minus sign

4 -2x+3 = 3

Combine like terms

7 -2x = 3

Subtract 7 from each side

7 -2x-7 = 3-7

-2x = -4

Divide by -2

-2x/-2 = -4/-2

x = 2

A rectangular prism is 10 inches long, 6 inches wide, and 4 inches high. What is the surface area of this prism in square inches

tatyana61 [14]

Answer:

The surface area would be 248 square inches.

Step-by-step explanation:

To find the answer of this, use the formula for area of a rectangular prism.

SA = 2lw + 2lh + 2wh

SA = 2(10)(6) + 2(10)(4) + 2(6)(4)

SA = 120 + 80 + 48

SA = 248

What do you do when your mom is crying? probably not the best place to ask but im grounded so i cant ask on any other platform l

FromTheMoon [43]

Answer:

Ask her why she is crying. If she explains why, listen and comfort her. If she says to "go away" or "i don't want to talk about it," give her space and come back later. She needs to let it out, so have patience :)

Hope this helps!!
