Answer: 672 square centimeters

Step-by-step explanation:

20 X 10 = 200

(16 X 12)/2 X 2= 192

10 X 12= 120

16 X 10=160

160 + 120 + 192 + 200 =672

Answer:

672 \:cm^2

Step-by-step explanation:

Find the area of the 2 triangle faces and the 3 rectangle faces, then add the areas together to get the total surface area of the triangular prism.

(16 \times 12 \times 1/2) \times 2 + (12 \times 10) + (16 \times 10) + (10 \times 20)

=672

Identify the exponent in the term –3x2. A. x B. 2 C. minus sign (–) D. 3
Vedmedyk [2.9K]

Answer:

B. 2

Step-by-step explanation:

Assuming the term is meant to look like this: -3x², then the answer is B.2. An exponent is a superscript (super means above, script means writing) that tells you to multiply something by itself.

In this case, -3x² means -3·x·x

If it was written as (-3x)², it would mean (-3x)·(-3x)

.The binomial (a + 5) is a factor of a2 + 7a + 10. What is the other factor?
Lubov Fominskaja [6]

Answer:

(a+2) Is your answer

Step-by-step explanation:

You could try synthetic division, but it's pretty complicated (not to mention for much harder problems), so you should try factoring this. What two numbers multiply up to 10 and add up to 7? Using trial and error, we would find these two numbers to be 2 and 5. Therefore, it factors into (a+5)(a+2).
