First, you should do the product first:
(-4.7)* (7.021)= -32.9987
Then, let's do the subtraction:
(-5.12)- (-32.9987)
= (-5.12)+ 32.9987
= 27.8787
Final answer: 27.8787
Hope this would help~
First, we need to multiply.
-4.7 * 7.021 = -32.9987
Now subtract.
-5.12 -(-32.9987) = -5.12 + 32.9987 = 27.8787
Final answer: 27.8787

Step-by-step explanation:
First we should simplify the formula. The simplified formula would be 1/3n+2/3. We then substitute 10 for n. (10/3)+2/3= 12/3=4.
Answer:
2x^2 + 8x - 9 = 0
2x^2 + 8x = 9
2x^2 + x = 9/8
x^2 + x = 9/8×2
x^2 + x = 9/16
2x = √9/16
x = √9/32
