The binomial expansion:
a = 2y, b = 4 x^3, n = 4
( x )^3k = x^ 9
k = 3
Answer: the coefficient is
512.
Answer:
Step-by-step explanation:
This is a right angled triangles and the summation of the other two angles must equal 90°
OR you can also say that the summation of all the angles in a ∆ must give us 180°
Therefore (2x+14) + (4x-26) = 90°
Expanding... By collecting all like terms, we have
2x+4x+14-26-90 = 0
6x - 102° = 0
Therefore, 6x = 102
x = 102/6
x = 17°
Answer:
25
Step-by-step explanation:
b=4x+1 h=x+1 A=175
A=bh
Substitute: 175=(4x+1)(x+1)
Expand: 175=4x^2+5x+1
Subtract 175
4x^2+5x-174=0
Solve w/quadratic formula
(-5 <u>+</u> sqrt(25+2784))/8
Simplify: x=6 or -29/4
Distance is positive, so x=6
4x+1=4*6+1=25
9 if your in k12 this is the answer trust me i just took the test
