3.	How to solve question 22?
Answer» Answer: ABO + OBE = 180° 165 + OBE = 180 OBE = 180 - 165 = 15 CEB = 75° [ Alternate interior ANGLES] CEB + BEO = 180 [LINEAR PAIR] BEO = 180 - 75 = 105 In triangle BEO, EBO + BEO + BOE ( or BOC) = 180 [ Interior Angle Sum property] 15 + 105 + BOC = 180 BOC = 180 - 120 BOC = 60°

3.

How to solve question 22?

Answer»

Answer:

ABO + OBE = 180°

165 + OBE = 180

OBE = 180 - 165 = 15

CEB = 75° [ Alternate interior ANGLES]

CEB + BEO = 180 [LINEAR PAIR]

BEO = 180 - 75 = 105

In triangle BEO,

EBO + BEO + BOE ( or BOC) = 180 [ Interior Angle Sum property]

15 + 105 + BOC = 180

BOC = 180 - 120

BOC = 60°

Divide rs 4800 in the ratio of 2:3

Answer»

$\huge\bf{Hey RealPoet!}$

$\huge\bf{Answer:-}$

1920:2880

Explanation:-

FIRST I will find the total parts of 2:3

Then, 2:3 = 2 + 3 = 5,then

after adding I get NUMBER 5 now I will DIVIDE number 4800 with 5 then with the answer u got when I divide I will multiply 960 with 2 and 3 ,and I get my answer

CALCULATION:-

$(2 : 3 = 2 + 3 = 5)$

$4800 \: \div \: 5 = 960$

$960 × 2 = 1920$

$960 × 3 = 2880$

$1920:2880$

7 is to the power x+1 - 7 is to the power x-1= 48 find x

Answer»

ANSWER:x=1

Step-by-step explanation:

7^(x+1)-7^(x-1)=48

Or, 7^x*7^1-7^x*7^(-1)=48

Or, 7^x*7-7^x*(1/7)=48

Or, 7×7^x-(7^x/7)=48

Or, 49×7^x-7^x=48×7

Or, 7^x(49-1)=48×7

Answer» Answer: Step-by-step explanation: Solve the equation x3 − 3x2 – 2x + 4 = 0 We put the numbers that are factors of 4 into the equation to see if any of them are correct. f(1) = 13 − 3×12 – 2×1 + 4 = 0 1 is a SOLUTION f(−1) = (−1)3 − 3×(−1)2 – 2×(−1) + 4 = 2 f(2) = 23 − 3×22 – 2×2 + 4 = −4 f(−2) = (−2)3 − 3×(−2)2 – 2×(−2) + 4 = −12 f(4) = 43 − 3×42 – 2×4 + 4 = 12 f(−4) = (−4)3 − 3×(−4)2 – 2×(−4) + 4 = −100 The only integer solution is x = 1.

Obtain all other zeros of a polynomial 2 x ki power 4 + 3 x cube minus 15 x square - 24 x minus 8 if two of its zeros are 2 root 2 and minus 2 root 2

Answer»

Answer:

Step-by-step explanation:

Solve the equation x3 − 3x2 – 2x + 4 = 0

We put the numbers that are factors of 4 into the equation to see if any of them are correct.

f(1) = 13 − 3×12 – 2×1 + 4 = 0 1 is a SOLUTION

f(−1) = (−1)3 − 3×(−1)2 – 2×(−1) + 4 = 2

f(2) = 23 − 3×22 – 2×2 + 4 = −4

f(−2) = (−2)3 − 3×(−2)2 – 2×(−2) + 4 = −12

f(4) = 43 − 3×42 – 2×4 + 4 = 12

f(−4) = (−4)3 − 3×(−4)2 – 2×(−4) + 4 = −100

The only integer solution is x = 1. When we have found one solution we don’t really NEED to test any other numbers because we can now solve the equation by dividing by (x − 1) and trying to solve the quadratic we get from the DIVISION.
