Write an algebraic expression to represent each phrase:
a. 4 more 7 times a number
b. 4 more than a number, then multiply the result by 7

A. 7n+4 B. (n+4)7

Step-by-step: A. Put it in simplest form(7n+4) or your teacher might count it wrong.

B. Make sure to use parentheses to tell them to do it first so when using PEMDAS or GERMDAS they don’t do the multiplication first, but the groups.

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
