Answer:

area = 4 \times ( \frac{1}{2}  \times base \times height) \\  =2 \times ( \frac{1}{2}  \times 16.3 \times 42.7) + 2 \times ( \frac{1}{2}  \times 16.3 \times 22.5) \\  = 696.01 + 366.75 \\  = 1062.76 \\  = 1063

If f(x)= 5x-3 what is f(-4)
Over [174]
Plug the -4 into equation

f(-4) = 5(-4) -3

multiply 5•-4= -20

then subtract -20-3

when you have two negatives you add

= -23
f ( - 4) = 5( - 4) - 3 =  - 23

Factorise fully the following:<br>a) x² + 2x<br>b) 2x² - 6x<br>c) 15x - 10x³<br>d) 9x² + 3x³​
Lostsunrise [7]

Answer:

a) x(x+2)

b) 2x(x-3)

c) 5x(3-2x^2)

d) 3x^2(3+x)

Step-by-step explanation:

a) x^2+2x

When factoring a binomial (a polynomial with two terms), what we will be looking for are the terms that are shared between them.

In this problem, it can be seen that both of these terms have and x. This means that we can factor it out to get

x(x+2)

b) 2x^2-6x

What are the common terms here?

It can be seen that each of these share a 2x, so our factored form would be

2x(x-3)

c) 15x-10x^3

What about this one?

The common factor of this one is 5x, so our factored form would be

5x(3-2x^2)

d) 9x^2+3x^3

The common factor of this one is 3x^2, so our factored form would be

3x^2(3+x)
