Answer:
Step-by-step explanation:
I think it increased by 20% I think or it’s 25% think
60,40,35,45,39
Put in order from least to greatest
35, 39, 40, 45, 60
Range = Max - Min
Range = 60 - 35
Range = 25
Answer
D) 25
Answer:19. 17 degrees
20. 49 degrees
Step-by-step explanation:
Because of the postulate 50+?=67
So ?=17
And 20.
94+?=143
So
?=49
(Edit)I though you only meant 19 and 20
21. X=8
22. X=12
23.x=8
24.x=7
Step-by-step explanation:
We have:
x - y = 43 , xy = 15
To find, the value of x^2+y^2x
2
+y
2
= ?
∴ x - y = 43
Squaring both sides, we get
(x - y)^2(x−y)
2
= 43^243
2
⇒ x^2+y^2x
2
+y
2
- 2xy = 1849
Using the algebraic identity,
(a - b)^2(a−b)
2
= a^2+b^2a
2
+b
2
- 2ab
⇒ x^2+y^2x
2
+y
2
= 1849 + 2xy
Put xy = 15, we get
x^2+y^2x
2
+y
2
= 1849 + 2(15)
⇒ x^2+y^2x
2
+y
2
= 1849 + 30
⇒ x^2+y^2x
2
+y
2
= 1879
∴ x^2+y^2x
2
+y
2
= 1879
I will send hint follow this hint then slove it .
thankyou
I think the explanation is tha the harangued could be shanty of the Akamai
