Multiply the polynomials (5x^2+2x+8)(7x-6)

Step-by-step explanation:

In order to multiply you just have to go term by term, you just first multiply 7x by the whole trinomial:

()(7x)=

ANd then you multiply the second term: -6

()(-6)=

ANd now you just have to add them up together:

And this would be equal to:

1. 22

2. 1

3. 7

4. 18

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
