Median is a middle value
So it is 28
Would it be 9 because 8 times 3 equals 24 and 3 times 3 equals 9
9514 1404 393
Answer:
Step-by-step explanation:
To multiply two polynomials, each term of the first polynomial is <u>multiplied</u> to each term in the second polynomial. Combine any <u>like terms</u> to simplify.
Answer:
see below
Step-by-step explanation:
9 ^-5 * 9^-3
When multiplying these we ADD the exponents:
9^-5 * 9^-3
= 9^(-5 + -3)
= 9 ^-8
= 1/9^8 Option A
2. 2^14 / 2^7 This is a division so we SUBTRACT the exponents:-
= 2^(14 - 7)
= 2^7 (answer)
3. If the triangle is a right angled one then it will obey Pythagoras Theorem so:-
13^ = x^2 + 5&2
x^2 = 13^2 - 5^2
x^2 = 144
x = 12 (answer)
4. The last choice is a crucial step.
The total area of the triangles is the same in both large squares so the area of the large square e^2 = a^2 + b^2 ( the 2 squares in the left side large square).
