Answer:

x = 5

Step-by-step explanation:

The area (A) of the triangle is calculated as

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

Here b = 8 and h = 15 , then

A = \frac{1}{2} × 8 × 15 = 4 × 15 = 60 cm²

The area of the rectangle is also 60 cm² , then

length × breadth = 60 , that is

12x = 60 ( divide both sides by 12 )

x = 5

4. Determine the following difference. (2x² + 3x - 10) - (x² - x + 111)  please explain
SIZIF [17.4K]
Hi there! The answer is A.

(2x² + 3x - 10) - (x² - x + 111) 
Let's solve this problem step by step!

First work out the parenthesis. Because we multiply by negative 1, we mustn't forget to change the symbols in front of the factors.
2x² + 3x - 10 - x² + x - 111

Now rearrange our expression, in order to collect the terms later.
2x² - x² + x + 3x - 10 - 111

And finally collect the terms.
x² + 4x -121

The answer is A.
