Use the rational root theorem
a0=16, an=1
The dividers of a0: 1,2,4,8,16 The dividers of an:1
Therefore check the following rational numbers: +- 1,2,4,8,16/1
4/1 is a root of the expression, so factor out x-4,
compute (x^4+13x^3-64x^2-20x+16)/(x-4) to get the rest of the equation:
x^3+17x^2+4x-4
=(x-4)(x^3+17x^2+4x-4)/x-4
which will leave you with answer B
x^3+17x^2+4x-4
Answer:
135
Step-by-step explanation:
I am not sure if you have to use the substitution method but I just did (600 - 60) then divided by 4
Remember for any two polygons
Area of polygons is directly proportional to square of sides
So
- BC²/XY²=135/15
- 15²/XY²=9
- (15/3)²=XY²
- XY=5in
#35
- HJ²/XY²=168/378
- 8²/XY²=0.44
- XY²=64/0.44
- XY²=145.45
- XY\approx 12+
Answer:
C 16
Step-by-step explanation:
Using ratios
3:12
12/3=4
4:x
4*4=16
x=16
4:16
hope this helps:)
A triangle 45 – 45 – 90 degree (or isosceles right triangle) is a triangle with angles of 45°, 45°, and 90° and sides in the ratio of 1:1:√2
if hypo = 3√2 then side = 3
answer
a = b = 3
-------------------
<span>30-60-90 Triangle
</span>long leg = short leg times √3
hypo = twice the short leg
given long leg = 5√3
so
short leg = b = 5
hypo = c = 2(5) = 10
