Answer:

33

Step-by-step explanation:

First find the missing side...

11^2 + a^2 = 20^2

121 + a^2 = 400

400 - 121 = a^2

a^2 = 279

a = 16.7

A = 16.7, B = 11, C = 20

20 - 16.7 = 3.3

Estimate

3 x 11 = 33

vlada-n [284]

Answer:

<h2>x = 2, y = 6 → (2, 6)</h2>

Step-by-step explanation:

\bold{ELIMINATION\ METHOD}\\\\\left\{\begin{array}{ccc}y=-x+8\\y=x+4&\TEXT{change the signs}\end{array}\right\\\underline{+\left\{\begin{array}{ccc}y=-x+8\\-y=-x-4\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad0=-2x+4\qquad\text{add}\ 2x\ \text{to both sides}\\.\qquad2x=4\qquad\text{divide both sides by 2}\\.\qquad\boxed{x=2}\\\\\text{Put it to the second equation}\\y=2+4\\\boxed{y=6}

\bold{SUBSTITUTION\ METHOD}\\\\\left\{\begin{array}{ccc}y=-x+8&(1)\\y=x+4&(2)\end{array}\right\\\\\text{Substitute (1) to (2)}\\\\-x+8=x+4\qquad\text{subtract 8 from both sides}\\-x=x-4\qquad\text{subtract}\ x\ \text{from both sides}\\-x-x=-4\\-2x=-4\qquad\text{divide both sides by (-2)}\\\boxed{x=2}\\\\\text{Put it to the second equation}\\y=2+4\\\boxed{y=6}

Can someone help me with this pls?
Pavlova-9 [17]

Answer:

1176cm^{3}

Step-by-step explanation:

First, calculate the volume as if it was a full rectangle.

Volume formula:

length x width x height

16 x 6 x 21 = 2016cm^{3} (this is the volume if this was a full rectangle)

Now to calculate the size of the missing part we do the same thing

10 x 6 x 14 = 840cm^{3}

To work out the volume of this shape, we need to subtract the volume of the missing part from the volume of the rectangle

2016 - 840 = 1176cm^{3}

I hope this helped :-)
