21 cm squared
Step-by-step explanation:
The area of a triangle is base times height divided by 2, or
a = base time height/2
The base here is 7cm and the height is 6cm.
7 times 6 is 42.
42 divided by 2 is 21
Answer:
3(2 - y)(2 + y)(4 + y²)
Step-by-step explanation:
48 - 3y⁴
Take 3 common:
3(16 - y⁴)
16 is 4² and y⁴ is (y²)²
3(4² - (y²)²)
Using a² - b² = (a - b)(a + b)
3(4 - y²)(4 + y²)
Again, 4 = 2²
3(2² - y²)(4 + y²)
3(2 - y)(2 + y)(4 + y²)
Aye the Answer is D ~hope that helps :)
