Answer:

6(12+8)

Step-by-step explanation:

the word 'times' would indicate the multiplication of 2 numbers

the word 'sum' would indicate the addition of 2 numbers. in this case, 12 + 8 would be placed in parenthesis

hope this helps!! :)

Classify the numbers by writing them in the appropriate section of the Venn Diagram 1) L. 136, 8, 7, V140, V4,8, V8 , 2.89 Real

saveliy_v [14]

EXPLANATION:

Classification of numbers according to the Venn diagram:

Rational numbers:

These numbers are represented by a fraction a / b, where a and b are integers and also b is different from zero.

Whole numbers:

An integer is a natural number that can be positive or negative.

Natural numbers:

Natural numbers are those that start at zero to infinity are clearly positive.

Rational numbers:

When taking the square root of 8, 36 and 4 the result is an exact value that is why they are considered as rational numbers.

Irrational Numbers:

When the root of a number is not exact but is expressed as an infinite decimal as in the case of the square root of 140 which is 11.83215956619; this is an irrational number, also this result cannot be expressed as a fraction.

I need help with 4 and 5

krok68 [10]

4)
area of figure = bh = 8x10 = 80
same as a trapezoid have base 6 and 14 and height 8
because A of trapezoid = 1/2(6+14)*8 = 80
so answer is C
a trapezoid with bases of 6 mm and 14 mm and a height of 8 mm

5)
area of original figure A = bh = 8 x 10 = 80
if double h = 16 and b = 20 then A = 16 x 20 = 320
the area is quadrupled.

answer is C.
The area is quadrupled

How many different triangles can be constructed using angle measurements 81 52 and 47? I need the answer really fast and like ri

solniwko [45]

The options are:
A) exactly one triangle;
B) no triangles;
C) more than one triangle.

First thing, let's see if these angles can make a triangle:
(81 + 52 + 47) = 180

We know that the sum of the inner angles of a triangle must equal 180°, therefore yes, they can be angles of a triangle.

With only the measure of the angles and nothing about the sides, we can construct as many triangles as we want: try, indeed, to construct a triangle with given angles bus sides of your choice; then, double the sides. You will get a triangle that is twice the size, but the angles remained the same.

Hence, the correct answer is C) more than one triangle.
