Help I don't know what to put ​
olga55 [171]

Answer:

7

Step-by-step explanation:

plug in 3 where ever there is x

so

(4(3)+2)-7

use PEMDAS to solve from left to right

P: Parenthesis

E: Exponents

M: Multiplication

D: Division

A: Addition

S: Subtraction

so we got p so we do that first

(4(3)+2) --> 4 × 3 = 12 (Multiplication first like in PEMDAS)

(12+2) = 14

so then in the equation you are left with

(14)-7 = 7

answer is 7

Marco is studying a type of mold that grows at a fast rate. He created the function f(x) = 345(1.30)x to model the number of mol
Ivahew [28]

1.30 represents the rate of growth of the mold spores. This decimal is a representation of the percentage growth, which would be 130%.


Since the function is written in terms of weeks, x will equal 4 to represent the amount of spores after 4 weeks. Plug the value into the function:


345(1.30)^4 = \boxed{985.35}


Rounded to the nearest ones value, there will be 985 mold spores after 4 weeks.
