There is a pattern. Each number is added by 5. So take 22 and add 5 to get 27. Just repeat until you find your answer, which would be 42.
1) 3+2x and 4-5x ; they want the sum so ..... (3+2x)+(4-5x) .... 3+2x+4-5x ..... = -3x+7
This answer helps us figure out the sum of the complex numbers because the "i" and "x" are just simply variables so the same simplification would apply.
2) 1-3x and 2+x ; They want us to find the product or multiplication of these two binomials: (1-3x)(2+x) ... To achieve this we use the FOIL method. We get:
2+x-6x-3x^2 ... = (-3x)^2 -5x+2.
The same reasoning applies just like number 1.
Area of sector=thita/360 ×pi×r^2
=60/360×22/7×5×5
=275/21
=13.0952
=13.1 inch^2
Answer:
x = -4, 10
Step-by-step explanation:
We take the square root and use the fact of "plus-minus" and find two values of x. The process of solving this equation is shown below:
Hence the two values of x are -4 and 10
Note: both (-7)^2 and (7)^2 are 49 . So we took "plus-minus" values of
