Mathematics
1 answer:
Setler [38]3 years ago

<h2>Answer: </h2>

1. <u>Area = b × h</u>

A = 5 × 3

A = 15cm².

2. <u>Area = ½(a + b) × h</u>

A = ½(9 + 15) × 15

A = ½ × 24 × 15

A = 12 × 15

A = 180mm².

3. <u>Area = 2(l × b) + l × b</u>

A = 2(12 × 4) + 6 × 3

A = 2 × 48 + 18

A = 96 + 18

A = 114m².

Y=3x²+3x+1,find the value of the discrimination​
Rufina [12.5K]

Answer:

Step-by-step explanation:

a = 3

b = 3

c  = 1

Discriminate = sqrt(b^2 - 4ac)

Discriminate = sqrt(9 - 4*3*1)

Discriminate = sqrt(9 - 12)

Discriminate = sqrt(-3)

What negative value means that there are no real roots and the y intercept = 1. You should always graph this kind of question, which I am doing for you. I use Desmos which is a very handy program.

You should notice that the minimum is above the x axis. That means there are no real roots, just as the discriminate tells you.

What is the area of this triangle 12in 3in
grin007 [14]

Answer:

Step-by-step explanation:

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

Two rectangles are similar. The ratio of their corresponding sides is 1:4.
larisa [96]

ratio of perimeter is the same as ratio of sides so perimeter would be 1:4

since area is in square units you need to square the ratio (1:4)^2 which is 1:16
