How to solve 4+6 (8)

Mathematics
1 answer:
Ber [7]3 years ago

We can solve this using the rules about order of operations. They tell us that we should start by multiplying the 6 and 8. 8 times 6 equals 48, so our new problem is 4 plus 48. We can simply add these together and see that 52 is the correct answer.

Find the product: (6x^2+8)(3x^2-5x+7)
Leno4ka [110]

Answer:

18x⁴ - 30x³ + 66x² - 40x + 56

Step-by-step explanation:

1) Distribute

  • (6x² + 8) (3x² - 5x + 7)
  • 6(3x² - 5x + 7) x² + 8(3x² - 5x + 7)

2) Distribute

  • 6(3x² - 5x + 7) x² + 8(3x² - 5x + 7)
  • 18x⁴ - 30x³ + 42x² + 8(3x² - 5x + 7)

3) Distribute

  • 18x⁴ - 30x³ + 42x² + 8(3x² - 5x + 7)
  • 18x⁴ - 30x³ + 42x² + 24x² - 40x + 56

4) Combine like terms

  • 18x⁴ - 30x³ + 42x² + 24x² - 40x + 56
  • 18x⁴ - 30x³ + 66x² - 40x + 56

This is my question​
Talja [164]

Answer/Step-by-step explanation:

∆ABC is similar to ∆CDE. Therefore, the ratio of their corresponding sides are proportional.

This,

\frac{DE}{AB} = \frac{DC}{AC}

\frac{4}{3} = \frac{x + 3}{x + 1}

Solve for x

4(x + 1) = 3(x + 3)

4x + 4 = 3x + 9

4x + 4 - 4 = 3x + 9 - 4

4x = 3x + 5

4x - 3x = 3x + 5 - 3x

x = 5

Use the value of x to find AC and DC

AC = x + 1 = 5 + 1 = 6

DC = x + 3 = 5 + 3 = 8
