Answer:
the length of FC = b = 12 cm
Step-by-step explanation:
The volume of prism is given along with height and height of triangular base. WE need to find the length of base.
V= B*h
where B= area of base = 1/2 * b *h
V= ( 1/2 *b * h) * h
900= 1/2 * b * 10 * 15
900 * 2 = b* 150
1800 = b* 150
=> b= 1800/150
b= 12 cm
So the length of FC = b = 12 cm

Answer: i don't know but it could be 1
Step-by-step explanation:
Prime factorization is the process of finding the factors of a number and these factors must be of prime numbers.
27000 = 27 × 10000
27000 = 27 × 10⁴
27000 = 3 × 9 × 10⁴ [Here we have 3 as a prime number, but not '9' and '10', so we will keep breaking this down]
27000 = 3 ×3 × 3 × (2 × 5) ⁴ [Here we have all prime numbers]
27000 = 3³ × 2⁴ × 5⁴
Answer:
-4x² - 2xy + 5y²
Step-by-step explanation:
Step 1: Write expression
(3x² - 5xy + 2y²) - (7x² - 3xy - 3y²)
Step 2: Distribute negative
3x² - 5xy + 2y² - 7x² + 3xy + 3y²
Step 3: Combine like terms
-4x² - 2xy + 5y²
