Question

add the following: x^2, -a^2, - 5x^2, +2a^2, -4x^2 + 4a^2​

Answer 1

Answer:

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Answer 2

Step-by-step explanation:

1.

➣ Arithmetic mean = \boxed{\bf{\color{yellw}{\: \frac{a \: + \: b \: }{2} }}}

2

a+b

➣ A.M = {\bf{\color{yellw}{ \: \frac{71 \: + \: 23 \: }{2} }}}

2

71+23

➣ A.M = {\bf{\color{yellw}{ \: \frac{ \: 94 \: }{2} }}}

2

94

➣ A.M= 47

2.

Correct Question:-

Sum of the 14 arithmetic mean between 3 and 23 is

Solution:-

Given,

Number of A.M = 14

First term(a) = 3

Last term(b) = 23

➣ {\bf{\color{yellw}{n \: \times \: \frac{a \: + \: b \: }{2} }}}n×

2

a+b

➣ {\bf{\color{yellw}{14 \: \times \: \frac{2 \: + \: 23 \: }{2} }}}14×

2

2+23

➣ {\bf{\color{yellw}{14 \: \times \: \frac{ \: 25 \: }{2} }}}14×

2

25

➣ 175

Note:- Sum of " n " A.M between a and b is n(a + b/2)
