Answer:
H(4)=16
Step-by-step explanation:
there is no H(16) on the graph
you can see that 4 on the abscissa axis(horizontal) corresponds with 16 on the ordinate axis(vertical)
try c im sorry if im wrong i tried
Answer:
If you combine everything its <em>-4y+3x-9</em>
Step-by-step explanation:
Answer:
<em>perimeter</em><em> </em><em>of </em><em>figure</em><em> </em><em>A </em><em>is </em><em>4</em><em>0</em><em> </em><em>cm</em>
<em>.</em><em>.</em>
<em>breadth </em><em>of </em><em>figure</em><em> </em><em>B </em><em>is </em><em>3</em><em>.</em><em>3</em><em>3</em><em>. </em><em> </em><em>{</em><em>ie,</em><em>3</em><em> </em><em>whole </em><em>4</em><em> </em><em>by </em><em>1</em><em>2</em><em>}</em>
This may not be very pretty.
(2x + 5) * (2x + 5) expanded is (use foil)
F = 4x^2
O = 2x * 5 = 10x
I = 2x + 5 = 10x
L = 25
Total = 4x^2 + 20x + 25
(x + 3)(x + 3) = x^2 + 6x + 9 by the same method
(2x + 7)(2x + 7) = 4x^2 + 28x + 49 Same method.
4x^2 + 20x + 25 + x^2 + 6x + 9 = 4x^2 + 28x + 49
5x^2 + 26x + 34 = 4x^2 + 28x + 49 Collect everything on the left.
x^2 - 2x - 15 = 0
(x - 5)(x + 3) = 0
x + 3 will have no meaning.
x - 5 = 0
x = 5
2x + 5 = 2*5 + 5 = 15
x + 3 = 5 + 3 = 8
2x+ 7 = 2*5 +7 = 17
Check
15^2 + 8^2 = 17^2
225 + 64 = ? 289
289 = 289
a = 15 <<<<< answer
b = 8 <<<<< answer
c = 17 <<<<< answer
