A shape is made of 12 right triangles of equal size. Each right triangle has a base of 4cm and a height of 5cm. What is the tota

Natalka [10]

Answer: 120 cm²

Step-by-step explanation:

Let's start by finding the area of one triangle

The formula for finding the area of a triangle is $A=\frac{hb}{2}$

Where

A is the area

h is the height (5 for this)

and b is the base (4 for this)

Let's sub in our values and solve.

$A=\frac{(5)(4)}{2}\\A=\frac{20}{2}\\A=10$

Since there are 12 triangles in the shape we must multiply our area for one triangle by 12 to find the total area of the shape

12×10=120

A polynomial equation with rational coefficients has the roots -8 and 2-i. Find two additional roots

shutvik [7]

Answer:

Step-by-step explanation:

If the polynomial is a cubic (third-degree), then it is

f(x) = x³+4x²-27x+40

and the other root is 2+i.

However, if we need two additional roots, it implies that the polynomial is a quartic (fourth degree). In that case, we need additional information. Reread the original question and update post if necessary.

Find the domain of g(x)=1-2x^2

Ivan

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
