8 0

Answer:

Step-by-step explanation:

The slant height of one side of this pyramid is 5, and the base of this side is 4. Thus, the area of one slant side is (1/2)(5)(4) = 10 units^2.

There are 4 such sides. Thus, the total slant surface area is 4(10 units^2), or 40 units^2.

If you also want to include the base area, the total would be

40 units^2 + 16 units^2 = 56 units^2.

GREYUIT [131]

Answer:

7:15 A.M.
1 hour and 45 min = 105 min
3 hour 45 min= 225 min
1 hour and 15 min = 105 min
105(2)+ 225= 435 min= 7 hours and 25 min.

What is the answer for this

Eva8 [605]

1). 2x-1=5 (cause x can really be anything) solve the equation to get x=3 or in this case, triangle = 3.

2). Using the info from above, we get the equation 3+x=1.
Solving this equation we get, x (square) =-2.

3). Using all the info from the above problems we get the equation: 3-2*-2=x
Solving that we see that x (star) equals 7.

In conclusion:

Triangle=3
Square=-2
Star=7
