6x7=42cm squared
Base x height = triangle area
10+18=28/2=14
14x5=70cm squared
Add the parallel line together and divide that number by 2 then times that number by the height.

Answer:

Triangle - 21 units

Trapezoid - 65 units

Step-by-step explanation:

  • Because this triangle and trapezoid are reflections of each other when split in half, remove the highlighted parts to make them a rectangle. When made into a rectangle, you can use the formula length * width to find the area of either shape (trapezoid or triangle).
  • Note you won't be able to do this when solving for the area of ALL trapezoids and triangles.

The product of a binomial and trinomial is x^3+3x^2-x+2x^2+6x-2 which expression is equivalent to this product after it has been
Debora [2.8K]

Answer: First option.

Step-by-step explanation:

You know that the product obtained by multiplying a binomial and a trinomial is:

x^3+3x^2-x+2x^2+6x-2

Then, in order to simplify this product, it is necessary to add the like terms.

Therefore, the expression that is equivalent to this product after it has been fully simplified is:

 =x^3+(3x^2+2x^2)+(6x-x)-2\\\\=x^3+5x^2+5x-2

You can  observe that this matches with the first option.
