Hello!
You start with 13 1/4 inches of steel
You cut 2 3/4
So yo subtract these two
13 1/4 - 2 3/4 = 10 2/4
Then you cut 3 1/4 inches off
You subtract these as well
10 2/4 - 3 1/4 = 7 1/4
The answer is 7 1/4
Hope this helps!
Answer:
158 in²
Step-by-step explanation:
<u>Surface area</u>
A = 2·(l·w + l·h + w·h)
= 2·(3in·8in + 8in·5in + 3in·5in)
= 2·(24in² + 40in² + 15in²)
= 2·(79in²)
= 158 in²

Answer:
D.
Step-by-step explanation:
A term in a polynomial is a single number or a number multiplied by any number of variables. A polynomial is a sum of terms.
The only thing that can be done with variables in a polynomial is to multiply them by numbers or other variables. In a polynomial, you cannot: divide by a variable (have a variable in a denominator), have a root of a variable, have a log of a variable, have a variable as an exponent, etc.
All expressions are polynomials except for D. In D., the negative exponents mean division by variables.
