Please help me with the questions

V = 899.24; LA = 608; SA = 702.66

Step-by-step explanation:

V = 768in³

LA = 608in²

SA = 692in²

Step-by-step explanation:

Volume:

7 x 12 ÷ 2 = 42

42 x 19 = 768

LA:

11 x 19 = 209

9 x 19 = 171

19 x 12 = 228

209 + 171 + 228 = 608

SA:

12 x 7 = 84

84 + 608 = 692

hope this is right:)

10 * 563.67 = 5636.7

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
