60+-90x would be equivalent.
The formula for this is
. Filling in accordingly,
. This simplifies to
and 36=6x. Therefore, x = 6 so the bases are 6 and 12.
Answer:
This is a polynomial.
Step-by-step explanation:
A monomial is a constant, a variable or the product of constants and variables.
A binomial is the sum or difference of two monomials.
A trinomial is the sum or difference of three monomials.
Anything more than three terms makes it a polynomial.
This has 4 terms; thus it is a polynomial.
Answer:
325 and 375 mph
Step-by-step explanation:
Given :
Distance between plane A and B = 2800
Recall :
Distance = speed * time
Let speed of A = v1
Speed of B = v2
v1 = v2 + 50
Time taken = 4 hours
Distance = speed * time
Total distance = 2800
2800 = v1 * 4 + v2 * 4
2800 = (4v1) + (4v2)
2800 = 4(v2+50) + 4v2
2800 = 4v2 + 200 + 4v2
2800 = 8v2 + 200
2800 - 200 = 8v2
2600 = 8v2
v2 = 2600/8
v2 = 325 mph
v1 = v2 + 50
v1 = 325 + 50
v1 = 375 mph
Answer:
a = 4
Step-by-step explanation:
a^2 + b^2 = c^2
a= ?
b= 3
c= 5 (c is always the hypotenuse)
*plug in given values
a^2 + 3^2 = 5^2
a^2 + 9 = 25
-9 -9
a^2 = 16
*find the square root
sqrt(a) = sqrt(16)
a = 4
