Answer:

D = 76.

Step-by-step explanation:

Given : 3x² - 10x = -2.

To find : What is the discrimination.

Solution : We have given 3x² - 10x = -2.

By the formula : ax² + bx + c = 0.

Discrimination (D) = b² - 4ac.

Here, a = 3 , b = -10 , c= 2.

D = (-10)² - 4(3) (2).

D = 100 - 24.

D = 76.

Therefore, D = 76.

$6 - 10x = 2 \\ - 10x = 2 - 6 \\ 10x = 4 \\ x = 4 \div 10$
thus x will be 2/5

Answer:

Step-by-step explanation:

Solving inequalities is easy, you just need to follow the standard rules of algebra. Also, when multiplying or dividing by a negative number, the inequality sign is reversed.

Step 1: Divide by 5

x < 2

Step 2: Check

5(1) < 10

5 < 10✔️

Step 3: Check Again

Since an inequality has multiple solutions, it is important to check at least 2, to determine if the entire range of solutions is true.

5(-6) < 10

-30 < 10✔️

Step 4: Verified Answer

x < 2

I'm always happy to help :)

Answer:

Step-by-step explanation:

i). $\frac{48a^3}{6a}=\frac{6\times 8\times a\times a^2}{6a}$

$=\frac{6a}{6a}\times 8a^2$

= 8a²

ii). $\frac{72a^3b^4c^5}{8ab^2c^3}$ = $\frac{8\times 9\times a\times a^2\times b^2\times b^2\times c^2\times c^3}{8ab^2c^3}$

= $\frac{8ab^2c^3}{8ab^2c^3}\times 9a^2b^2c^2$

= 9a²b²c²
