I need help ASAP the setup has to be like number one M

4.2+4x4+(2x9)

5.(5 divide 36 divided by 4)+4divide2

6. 2 divided by(5x4)-7+2

7(3+8) divided by 42 divided by 7+2

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
