Robert is a boy, so you only need the formula for a boy’s predicted height.

father’s height=x
fathers height=180
so, x=180

mother’s height=y
mother’s height=160
so, y=160

plug in x=180 and y=160 into the formula.
0.4(x+y)+42
0.4(180+160)+42

use GEMDAS to simplify.

G(Groupings)

0.4(180+160)+42
0.4(340)+42

M(Multiplication)
0.4(340)+42
136+42

A(Addition)
136+42
178

The predicted height of Robert when he is an adult is 178 cm.

The number 2 in the expression 5 + 2x is called the
steposvetlana [31]

Answer:

Step-by-step explanation:

The coefficient of x is simply a number. The x gives it it's meaning. So if the coefficient of x changed from 2 to 6 that would mean there would 6 x's being added to five, not 2.

For example if x=2.

instead of 5 + 2*2

(which equals 9)

it would be 5 + 6*2

(which equals 17).

The difference between the answers is 4x, as there are an additional 4x's.

Hope this helps :)
