1. 8c^2-26c+15= (4c-3) (2c-5). Break the expression into groups: =(8c^2-6c)+(-20c+15). Factor out 8c^2-6c: 2c(4c-3). Factor out -5 from -20c+ 15: -5(4c-3). Lastly factor out common term (4c-3) and thats how you'll get your answer (4c-3) (2c-5).

2. common factors for 270 and 360 is 90.To find this write the factors of each and find the largest one.270: 1, 270, 2, 135, 3, 90, 5, 54, 6, 45, 9, 30, 10, 27, 15, 18360: 1, 360, 2, 180, 3, 120, 4, 90, 5, 72, 6, 60, 8, 45, 9, 40, 10, 36, 12, 30, 15, 24, 18, 20
3. The factors for 8 a3b2 and 12 ab4 is 4. because 8: 1, 2, 4, 812: 1, 2, 3, 4, 6, 12.

4. 81a^2+36a+4= (9a+2)^2. Break down the expression into groups: (81a^2+18a)+(18a+4). Factor out 9a from 81a^2 +18a: 9a(9a+2). Factor out 2 from 18a+4: 2(9a+2). so the groups you got are now 9a(9a+2)+2(9a+2). Lastley factor out common term (9a+2) to get (9a+2) (9a+2). Finally you get the answer (9a+2)^2.

5. mn-15+3m-5n= (n+3)(m-5). factor out m from nm+3m: m(n+3). Factor out -5 from -5n-15: -5(n+3). And thats how you get the number (n+3)(m-5)

Hope this helped :) Have a great day

Answer:

1.(2c-5)(4c-3)

2.2\times 3^2\times 5

3.4ab^2

4.(9a+2)(9a+2)

4.(m-5)(n+3)

Step-by-step explanation:

1.We are given that

8c^2-26c+15

We  have to find the factor

Using factorization method

8c^2-20c-6c+15

4c(2c-5)-3(2c-5)

(2c-5)(4c-3)

2.We are given that 270 and 360

We have to find the HCF of 270 and 360

270=2\times 3^3\times 5

360=2^3\times3^2\times 5

Hence, HCF of 270 and 360 =2\times 3^2\times 5

3.We are given that 8a^3b^2 and 12ab^4

We have to find HCF

8a^3b^2=2^3\times a\times a\times a\times b\times b

12 ab^4=2^2\times 3\times a\times b\times b\times b\times b

Common factors are 4,a,b^2

Hence,HCF 8a^3b^2 and12 ab^4 =4ab^2

4.81a^2+36a+4

We have to find the factors

81a^2+18a+18a+4

9a(9a+2)+2(9a+2)

(9a+2)(9a+2)

5.mn-15+3m-5n

We have to find the factors

mn+3m-5n-15

m(n+3)-5(n+3)

(m-5)(n+3)

What are the coordinates of point Q?
Lady bird [3.3K]

Answer:

Q (-4, -2); 2 units; Q' will be above the x-axis; 2 unites; no; yes, the y coordinates are multiplied by -1; Q' (-4, 2); R' (-2, 2), S' (1, 5), T' (-2, 5);

Step-by-step explanation:

even after a reflection over the x-axis, each points distance from the x-axis will stay the same

the x-coordinates don't change because the distance from the y-axis stays the same

the picture below shows points of Q'R'S'T', just connect the vertices
