Answer:

a) 5xy + 9yz + 3zx + 5x - 4y

Step-by-step explanation:

→ (7xy + 5yz - 3zx) + (4yz + 9zx - 4y) + (-3xz + 5x - 2xy)

→ (7xy - 2xy) + (5yz + 4yz) + (-3zx + 9zx - 3xz) + (5x) + (-4y)

→ 5xy + 9yz + 3zx + 5x - 4y

Hence, option (a) is the correct answer.

Answer:

\textsf{A)}\quad \sf 5xy+9yz+3zx+5x-4y

Step-by-step explanation:

Given expression:

\sf (7xy+5yz-3zx)+(4yz+9zx-4y)+(-3xz+5x-2xy)

Remove the parentheses:

\implies \sf 7xy+5yz-3zx+4yz+9zx-4y-3xz+5x-2xy

Collect like terms:

\implies \sf 7xy-2xy+5yz+4yz+9zx-3zx-3xz+5x-4y

Combine like terms:

\implies \sf (7-2)xy+(5+4)yz+(9-3-3)zx+5x-4y

\implies \sf 5xy+9yz+3zx+5x-4y

The relationship between sets of rational numbers is pictured below
REY [17]

The correct answer is G. Integers include whole numbers and natural numbers.

Explanation:

The graph presented shows the relationship between different sets of numbers. In this graph, the second most general category is integers, and this covers or includes two smaller categories which are whole numbers and natural numbers. This means the whole and natural numbers are part of integers.

Indeed, integers include numbers such as 10, 256, or -6 because these can be expressed without using fractions or decimals. Also, this category includes whole or non-decimal numbers, as well as natural numbers, which are positive whole numbers such as 36 or 1546. According to this, the correct answer is G.

Can you help me with this question?
Rufina [12.5K]

Answer:

  16.2

Step-by-step explanation:

The angle internal to the triangle at B is the supplement of the one shown, so is 65°. That is equal to the angle internal to the triangle at D. Since the vertical angles at C are congruent, the two triangles are similar by the AA theorem.

Corresponding sides of similar triangles are proportional, so we can write the proportion shown in the attachment:

  BC/FC = DC/AC

  BC = FC(DC/AC) = 21.6(7.2/9.6)

  BC = 16.2 . . . . matches the first choice
