Answer:

Step-by-step explanation:

Triangle:

Base = 4 units

Height = 3 units   {perpendicular height}

Area=\frac{1}{2}*base*height\\\\=\frac{1}{2}*4*3\\\\=2*3

= 6 square units

Rectangle:

To find the area count the number of squares. Number of square = 6

Area = 6 square  units

or You can find the area of the rectangle as bellow also

Length = 3 units

Width = 2 units

Area = length*width

       = 3*2

       = 6 square units

Both the triangle and rectangles has the same area 6 square units

Answer these 4 for me please help me step by step
tangare [24]

4.

The equation we have is:

\frac{8}{5}a=-6

To solve for "a", we want to isolate it in one side.

For this. we can start by multiplying each side by 5. This will make the denominator to cancel out:

\begin{gathered} 5\cdot\frac{8}{5}a=5\cdot(-6) \\ 8a=-30 \end{gathered}

Now, we can divide both sides by 8, which will cancel the coefficient 8 multiplying "a":

\begin{gathered} \frac{8a}{8}=-\frac{30}{8} \\ a=-\frac{15}{4} \end{gathered}

And that is the answer to 4.
