. only answer if you will actually help pls!!!!!!!!
xxMikexx [17]

Answer:

5820 square inches

Step-by-step explanation:

For the rectangular prism in the middle:

24*30=720*2=1140

10*30=300*2=600

1140+600=1740

For the left triangular prism:

10*24=240

26*30=780

24*30=720

10*30=300

240+780+720+300=2040

For the other right triangular prism, it's the same.

Let's add now to find the surface for the whole ramp.

1740+2040+2040=5820

Hope this is helpful to you

If x=3 is a solution of the equation 2x²-5x+k=0 find the value of k​
Novosadov [1.4K]

Answer:

k = - 3

Step-by-step explanation:

Given that x = 3 is a solution then it satisfies the equation, that is

2(3)² - 5(3) + k = 0

2(9) - 15 + k = 0

18 - 15 + k = 0

3 + k = 0 ( subtract 3 from both sides )

k = - 3

Find a polynomial f(x) of degree 3 with real coefficents and following zeros. -4,4i
ElenaW [278]

Answer:

f(x)=x^3 +4x^2 +16x +64

Step by step explanation:

\text{Given that,  two roots are}~ -4~ \text{and}~  4i.\\\\\text{Let,}\\\\~~~~~~~x = 4i\\\\\implies  x^2 = 16i^2~~~~~~~;[\text{Square on both sides}]\\\\\implies x^2 = -16~~~~~~~~;[i^2 = -1]\\\\\implies x^2 +16 = 0\\\\\text{So,}~ x^2 +16~ \text{ is a factor of the 3 degree polynomial}.\\ \\ \text{The polynomial is ,}\\\\ f(x) = (x+4)(x^2 +16)\\\\~~~~~~~=x^3 +16x +4x^2 +64\\\\~~~~~~~=x^3 +4x^2 +16x +64
