Answer:
Diameter = 49
radius = 49/2
circumference of circle is = <em>2</em><em>π</em><em> </em><em>r</em>
<em>=</em><em>. </em><em> </em><em>2</em><em>*</em><em>2</em><em>2</em><em>/</em><em>7</em><em>*</em><em>4</em><em>9</em><em>/</em><em>2</em>
<em>=</em><em> </em><em>1</em><em>5</em><em>4</em><em> </em><em>cm</em>
<em>hope</em><em> it</em><em> helps</em>
Your question is a difference of squares. both terms that need to be factored are squared. to solve take the square root of each put into two terms one of addition and one of subtraction.
anwser= (5x-9)(5x+9)
the reason this works is because when you foil you get
25x²-45x+45x-81
the middle terms cancel revealing
25x²-81
Answer:
7/4
Step-by-step explanation:
They all have to have common denominators
The common denominator is 32
3/4= multiply by 8/8= 23/32
3/16= multiply by 2/2= 6/32
11/32. Is. 11/32
1/8 multiply by 4/4 =. 4/32
Smallest to greatest is 1/8. 3/16. 11/32. 3/4
X × 75% = £45
x = £45 / 75%
x = £45 / 0,75
x = £60
