a&c but idk the other one. it might be d

Step-by-step explanation:

B, D & E

Step-by-step explanation:

Volume = ⅓×base area×height

40 = ⅓× BA × 4

BA = 30

A) Base area = 5×2 = 10

B) Base area = 3×10 = 30 (yes)

C) Base area = ½×10×3 = 15

D) 13² = 5² + side²

side² = 169-25 = 144

side = 12

Base area = ½×12×5 = 30 (yes)

E) Base area = 30 (yes)

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
