The universal order of operation is addition, subtraction, multiplication, division, exponentiation, and grouping. One thing to remember these is PEMDAS which is P for please, E for excuse, M is for my, D is for dear, A is for aunt, S is for Sally. PEMDAS actually means parentheses, Exponents, Multiplication, Division, Add, and Subtract.. Hope this helps!

PLEASE HELP ITS MATH THANK YOUUUU
NISA [10]
Answer: 10 meters

Explanation:

29 cm : blank meters

So how do we get from 348 cm to 29 cm?

To figure this out we divide.

348 divided by 28 = 12

we divided by 12 so we do the same with 120

120 divided by 12 = 10

So that’s the answer.

I hope this makes sense and helps you :)

What is the product of (3x+7) and (x-7) ?
sleet_krkn [62]

Answer: The product of (3x+7) and (x-7) equals 3x^2 + 28x + 49

Step-by-step explanation:

To find the product of (3x+7) and (x-7) means to multiply both variables: To multiply both variables, we first multiply 3x by the expression, x - 7, then multiply 7 by the expression, x - 7.

(3x × x) +( 3x × 7) + (7 × x) + ( 7 × 7)

= 3x^2 + 21x + 7x + 49

= 3x^2 + 28x + 49
