Factorising quadratic expressions
Multiply these brackets to remind yourself how to factorise.
<span><span>( x + 2 ) ( x + 5 ) = x2 + 7x + 10</span><span>( x + 2 ) ( x + 3 ) = x2 + 5x + 6</span><span>( x - 3 ) ( x - 5 ) = x 2 - 8x + 15</span><span>( x + 6 ) ( x - 5 ) = x2 + x - 30</span><span>( x - 6 ) ( x + 5 ) = x2 - x - 30</span></span>
Let x be the width , then the height = 4x
Area of this right triangle is x(4x)/2
Area = 4x²/2 = 32 m²
x² = 16
x = 4 m. If the width is 4 m, the height = 4 x 4 = 16 m
Answer:
Step-by-step explanation:
3x = 36 x 5
3x = 180
x = 60
Michael has 60 marbles.
Nick recieves 9 more marbles so he has 36 + 9 = 45 marbles
The new ratio will be:
=
3) 7.67 x 10 ^-2
4) 3.3 x 10 ^3
