Evaluate the expression when m=3. m 2 - 5m + 7​

-2

Step-by-step explanation:

Substitute 3 for m: (3)2 - 5(3) + 7

Simplify: 6 - 15 + 7

Follow PEMDAS and subtract 6 from 15: -9 + 7

Add: -2

Hope this helps ^-^

You said m = 3.

Replace every m you see with 3.

m^2 - 5m + 7

(3)^2 -5(3) + 7

9 - 15 + 7

-6 + 7 = 1

Answer is 1.

answer: i literally just answered this question but they want me to do it again

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48
