Answer:

It increases it by 9.

Step-by-step explanation:

Given the following data;

Base = 4m

Height = 5m

Area of triangle = ½*base*height

Area of triangle = ½*4*5

Area of triangle = 2 * 5

Area of triangle = 10 m²

Multiplying the parameters by 3, we have;

Base = 4 * 3 = 12m

Height = 5 * 3 = 15m

To find the area of triangle;

Area of triangle = ½*base*height

Area of triangle = ½*12*15

Area of triangle = 6 * 15

Area of triangle = 90 m²

Therefore, multiplying the dimensions by a factor of 3 increases the area by 9.

Which of the following is not a zero of f(x) = (x2 - 4x + 4) (x2 + 3x - 10) = 0
Alenkinab [10]

Answer:

Only 2 and -5 are roots. Any other number is not a root.

Step-by-step explanation:

The zeros of the function are the x-intercepts and are found by factoring the equations and solving for x using the zero product property.

The f(x) = (x2 - 4x + 4) (x2 + 3x - 10) = 0 can factor into

f(x) = (x -2)(x-2)(x+5)(x-2) = 0.

Set each factor equal to 0 and solve.

x - 2 = 0 so x = 2. This repeats twice.

x + 5 = 0 so x = -5.

So the zeros are 2, -5.
