I think the answer would be 57.75
The scale factor is what you will use to make a whole shape bigger. For example if I have a square that all sides are 3 cm and the scale factor is 5 then the new square would have all sides 15 cm. So the length multiplied by the scale factor gives you the new length so then you take the new measurements and multiply them to get your new area. Hope this helps!!!!
Answer:1
Step-by-step explanation:
(x+2)(x+3)
x^2+3x+2x+6
x^2+5x+6
Therefore the coefficient of x^2 is 1
Answer:
d=4
Step-by-step explanation:
SUM OF 15 terms = 615
T5 = 53
T5 = a+(n-1)d
53 = a + 4d
4d = 53 - a
d = (53-a)/4
S15 = 15/2 (2a+14d) =615
15/2 [2a + 14×(53-a)/4 ]
=15/2 [ 2a +(53×14 - 14a )/4 ]
=15/2 [ (8a +742 - 14a ) /4]
615×8 = 15(-6a +742)
-6a+72=615×8/15 =41
-6a+72=42
-6a = - 72 + 42 = -30
a = 30/6= 5
a = 5
T5 = 5 + 4×d = 53
4d= 53 - 5 = 48
4d=48
d=4
Common difference is 4
Slope = y1-y2 / x1-x2 = -11-7 / 7-16 = -18/-9 = 2
