Problem 1

SA = 430.0

Step-by-step explanation:

13*11=143 divided by 2 is 71.5 (front face of the figure)

13*11=143 divided by 2 is 71.5 (backk face of the figure)

13*7=91 (left side rectangle)

17*7=119 (right side face rectangle)

11*7=77 (base)

Add all together 71.5+71.5+91+119+77=430.0

Problem 2

10*9=90 divided by 2 = 45 (front face triangle)

10*9=90 divided by 2 = 45 (back face triangle)

10*9=90 (right side rectangle face)

10*13.5=135 (left back side rectangle face)

10*10=100 (base)

Add everything together

45+45+90+135+100=415.0

Hope this helps!

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

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
