Answer:

The answer is C=6p3 + 29p2 + 22p – 21

Step-by-step explanation:

To calculate the product, we need to multiply each member of each multiplier:

(2p + 7)(3p2 + 4p – 3) = 2p · 3p² + 2p · 4p + 2p · -3 + 7 ·3p² + 7 · 4p + 7 · -3

= 6p³ + 8p² - 6p + 21p² + 28p - 21

= 6p³ + 8p² + 21p² + 28p - 6p -21

= 6p³ + 29p² + 22p - 21

Therefore, the product of (2p + 7)(3p2 + 4p – 3) is 6p³ + 29p² + 22p -21

Given: LM ∥ KN , KL ∥ NM LP = h1 = 5 cm, MQ = h2 = 6 cm PKLMN = 42 cm Find: Area of KLMN

andreev551 [17]

Answer:

Area = 630/11 cm² = 57 3/11 cm²

Step-by-step explanation:

Area = (5 cm)(KN) = (6 cm)(KL)

Perimeter = 2(KN +KL) = 42 cm

So, ...

KN = 1.2·KL . . . . divide the area equation by 5 cm

1.2·KL +KL = 21 cm . . . . . divide the perimeter equation by 2

KL = (21 cm)/2.2 . . . . . . . divide by the coefficient of KL

Substituting for KL in the area equation, we have ...

Area = (6 cm)(21 cm)/2.2 = 630/11 cm²

A box contains 4 bags of flour. The total mass of all 4 bags is 6kg. What is the mass of each bag in grams?

vovangra [49]

Answer:

1500 g

Step-by-step explanation:

To find the mass of each bag, we divide 6 kg by 4.

(6 kg)/4 = 1.5 kg

Now we convert 1.5 kg to g.

1 kg = 1000 g

1.5 kg * (1000 g)/(1 kg) = 1500 g

Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point (-2, 3)

Point (9, 3)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute [DF]: $d = \sqrt{(9+2)^2+(3-3)^2}$
Add/Subtract: $d = \sqrt{(11)^2+(0)^2}$
Simplify: $d = \sqrt{(11)^2}$
Simplify: $d = 11$
