EASY QUESTION

Focus on question 5

84 cm^3

14080 cm^3

81 cm^3

Step-by-step explanation:

Remember the formulas for volume, and you're golden.

a) V(prism) = area of base * height

                  = 12 cm^2 * 7 cm = 84 cm^3

b) V(prism) = area of base * height

                  = 88 cm^2 * 160 cm = 14080 cm^3

c) V(cylinder) = area of base * height

                      = 54 cm^2 * 1.5 cm = 81 cm^3

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

i think asking google will you get the answer to that question
