1. Work out area of rectangle = 9x8=72ft^2
2. Work out base of triangle
13-9=4ft
3. Work out the area of triangle =
4x8=32ft^2 (you don’t need to half it as the base is halved)
4. Add them together=
72+32=104ft^2
Hope this helps

Y=2X-1 5x-4y=1 is (1,1) a solution of the system

Natasha2012 [34]

You are given the system of equations

$\left\{\begin{array}{l}y=2x-1\\5x-4y=1.\end{array}\right.$

If you want simply to know whether (1,1) is a solution of this system, then substitute x=1 and y=1 into both equations:

$\left\{\begin{array}{l}1=2\cdot 1-1\\5\cdot 1-4\cdot 1=1\end{array}\Rightarrow \begin{array}{l}1=1\\1=1\end{array}\right.$

This means that (1,1) is a solution, because both iqualities hold.

3. If log 2 =a and log 3=b, the expression 9/32 is equivalent to

klemol [59]

Answer:

$\frac{9}{32} = \frac{{10}^{2b} }{{10}^{5a}}$

Step-by-step explanation:

It is given that:

log 2=a and log 3=b

This implies that:

$2 = {10}^{a}$

and

$3 = {10}^{b}$

Now we know that:

$\frac{9}{32} = \frac{ {3}^{2} }{ {2}^{5} }$

We substitute to get:

$\frac{9}{32} = \frac{ ({10}^{b}) ^{2} }{( {10}^{a})^{5} }$

We simplify to get:

$\frac{9}{32} = \frac{{10}^{2b} }{{10}^{5a}}$

Polynomials Multiply 5x(x2 - 4x + 2)

salantis [7]

Answer:

Assuming "x2" is x squared:

5x(x2-4x+2)

(5x(x2)+5x(-4x)+5x(2))

5x^3-20x+10x

For these polynomial multiplication problems, just distribute the number outside the parentheses.
