Ab = 12

A+b = 7

As a + b = 7,

A and b must be less than 7

A =6

B =2

Ab = 12

6 x 2 = 12

Help! What is the area of each shape?
choli [55]

Answer:

27.84 m² , 42.48 m²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = \frac{1}{2} bh ( b is the base and h the perpendicular height )

Shape A

has b = 9.6 and h = 5.8, then

A = 0.5 × 9.6 × 5.8 = 27.84 m²

Shape B

has b = 11.8 and h = 7.2 , then

A = 0.5 × 11.8 × 7.2 = 42.48 m²

If R is the set of all integers with absolute value less than 10, A is its subset containing all natural numbers less than 10 an
Elza [17]

Answer:

See explanation

Step-by-step explanation:

1. R is the set of all integers with absolute value less than 10, thus

R=\{a\in \mathbb{Z}\ :\ |a|

2. A is its subset containing all natural numbers less than 10, thus

A\subset R\\ \\A=\{b\in \mathbb{N}\ :\ b

3. B is the set of all integer solutions of inequality 2x+5<9 that are less than 10 by absolute value (and therefore, it is also a subset of R). First, solve the inequality:

2x+5

Thus,

B\subset R\\ \\B=\{c\in \mathbb{Z}\ :\ 2c+5

See the diagram in attached diagram.

Note that

A\cup B=R\\ \\A\cap B=\{1\}.
