Which shows the algebraic representation of the phrase and its value when n = 4.2? "twenty-eight plus the product of five and a number" 28 minus 5 n; when n = 4.2 the value is 7 28 + 5 n; when n = 4.2 the value is 49 28 n minus 5; when n = 4.2 the value is 112.6 28 n + 5; when n = 4.2 the value is 122.6

when n = 4.2 the value is 49

Step-by-step explanation:

Which shows the algebraic representation of the phrase and its value when n = 4.2?

"twenty-eight plus the product of five and a number"

Where the number = n

28 + 5n

n = 4.2

28 + 5(4.2)

28 + 21

= 49

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
