Question

2*(3 *3.5 - 2) -4*(2*3.5-5).​

Answer 1

Answer:

$\Huge \boxed{9}$

Step-by-step explanation:

Remember to use order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, & Subtract) the numbers from left to right.

Please Excuse My Dear Aunt Sally!

First, multiply numbers from left to right.

$\displaystyle 3.5*3=10.5$

$\displaystyle 2(10.5-2)$

Subtract numbers from left to right.

$\displaystyle10.5-2=8.5$

$\displaystyle 2*8.5=17$

$\displaystyle 4(2*3.5-5)$

$\displaystyle 2*3.5=7$

$\displaystyle 4(7-5)$

Next, parenthesis.

$\displaystyle 7-5=2$

$\displaystyle 4*2=8$

Then, subtract numbers from left to right.

$\displaystyle 17-8=\boxed{9}$

As a result, the correct answer is 9.

Hope this helps!

Have a wonderful blessing day! :)

Good luck! :)

Thanks!

Now Let's Head to the Question

$\bold{\rightarrow \: 2(3 \times 3.5 - 2) - 4(2 \times 3.5 - 5)}$

$\bold{\rightarrow \: 2(10.5 - 2) - 4(7 - 5)}$

$\bold{\rightarrow \: (2 \times 8.5) - (4 \times 2)}$

$\bold{\rightarrow \: (17 - 8)}$

$\bold{\purple{ \huge\rightarrow \: 9}}$
