Answer:
(4x² + 3)(16
- 12x² + 9)
Step-by-step explanation:
A sum of cubes factors as
a³ + b³ = (a + b)(a² - ab + b²)
64
= (4x²)³ ⇒ a = 4x²
27 = 3³ ⇒ b = 3
Hence
64
+ 27
(4x² + 3)((4x²)² - (4x² × 3) + 3²)
= (4x² + 3)(16
- 12x² + 9)
Answer: Area is 2250 and the peremiter is 210
Step-by-step explanation:
Answer:
5(2x-8)+15=-15
10x-40+15=-15
10x-25=-15
+25 +25 (add 25 to both sides)
____________
10x=10
divide by 10 on both sides
x=1
