Answer: y is 5
Step-by-step explanation: The triangle on the left is double the triangle on the right. Since 10 on the bigger triangle is double, it would be half on the smaller triangle, so 5.
Answer:
42.08inches
Step-by-step explanation:
Given data
SIze of TV= 50 inch
Width= 27inches
Length= ??
Applying Pythagoras theorem
z^2= x^2+y^2
50^2= x^2+27^2
square root both sides
50^2= x^2+27^2
2500= x^2+ 729
2500-729=x^2
1771=x^2
x= √1771
x= 42.08
Hence the lenght is 42.08inches
Answer:
3x²+4x-2
Step-by-step explanation:
-
are not like terms. To make them like terms, you have to multiply the first fraction by 3x, and the second by 2.
This makes it 
-
, which can be expanded to 
-
.
This can be simplified to 
.
The numerator is therefore 3x²+4x-2.
