Mathematics
1 answer:
S_A_V [24]3 years ago
6 0

Answer:

50 cm² and 56 cm²

Step-by-step explanation:

The area (A) is calculated as

A = \frac{1}{2} × d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )

(2)

A = \frac{1}{2} × (8 + 2) × (5 + 5)

   = 0.5 × 10 × 10

   = 5 × 10

    = 50 cm²

(3)

A = \frac{1}{2} × (12 + 2) × (4 + 4)

   = 0.5 × 14 × 8

   = 7 × 8

    = 56 cm²

vlada-n [284]

Answer:

3300 people

Step-by-step explanation:

There are 1000 households in a town. Specifically, there are

100 households with one member

= 100 × 1 member

= 100 people

200 households with 2 members

= 200 × 2 members

= 400 people

300 households with 3 members

= 300 × 3 member

= 900 people

200 households with 4 members,

= 200 × 4 members

= 800 people

100 households with 5 members

= 100 × 5 members

= 500 people

100 households with 6 members.

= 100 × 6 member

= 600 people

Thus, the total number of people living in the town is

100 people + 400 people + 900 people + 800 people + 500 people + 600 people

= 3300 people

What are the factors of the trinomial? Check all that apply
zmey [24]

For this case, the first thing we should do is write the trinomial.

To do this, we add similar terms.

We have then:

x ^ 2 + 2x - 7x - 7 - 7

Then, rewriting the trinomial we have:

x ^ 2 + 2x - 7x - 14

Then, the trinomial is given by:

x ^ 2 - 5x - 14

Factoring we have:

x (x + 2) -7 (x + 2)

Rewriting we have:

(x + 2) (x-7)

Answer:

The trinomial factors are given by:

(x + 2)\\(x-7)
