Answer:
-25
Step-by-step explanation:
2a² - 5a + 4, for f(-3)
2(-3)² -5(-3)+4
2*(-27)+15+4
-54+19
= -25
2b 2a
----------------- + -----------------
(b+a)^2 (b^2 - a^2)
2b 2a
= ----------------- + -------------------
(b+a)(b+a) (b+a)(b-a)
2b(b - a) + 2a(b + a)
= ------------------------------------
(b+a)(b+a)(b-a)
2b^2 - 2ab + 2ab + 2a^2
= ---------------------------------------
(b+a)(b+a)(b-a)
2b^2 + 2a^2
= ------------------------
(b+a)(b+a)(b-a)
2(b^2 + a^2)
= ------------------------
(b+a)^2 (b-a)
Answer:
Numerator: 2(b^2 + a^2)
Denominator: (b+a)^2 (b-a)
Answer:
area = 160160 inches²
area = 1.6016 × 10⁵ inches²
Step-by-step explanation:
The length of the rectangular computer chip is 22 × 10 cm and the width is 7 × 104 cm .
The area of the rectangular computer chip is the product of the length and the width.
area = length × width
area = (22 × 10) × (7 × 104)
area = 220 × 728
area = 160160 inches²
In scientific notation
area = 1.6016 × 10⁵ inches²
160160 is written as 1.6016 × 10⁵ because 1.60160 × 100000 = 1.6016 × 10⁵
