Answer:

Step-by-step explanation:

x 6 a

8 48 c

-4 b 20

Let the unknown numbers of the multiplication grid are a, b and c.

1). 6 × 8 = 48

2). (-4)×6 = b

b = -24

3). (-4) × a = 20

a = -5

4). 8 × a = c

8 × (-5) = c

c = -40

Therefore, missing in the given multiplication grid are,

x 6 -5

8 48 -40

-4 -24 20

Find the area of a triangle with a base length of 3 units and a height of 4 units.

svetlana [45]

Answer:

$6$ square units

Step-by-step explanation:

The area of a triangle can be calculated by multiplying the triangle's base by its height, and then dividing the result by $2$ . As an algebraic expression, this would be $\frac{bh}{2}$ , where $b$ is the triangle's base and $h$ is the triangle's height. In this case, we know that $b=3$ and $h=4$ . Therefore, the area of this triangle is $\frac{3*4}{2} =\frac{12}{2} =6$ square units. Hope this helps!
