Answer:
-x^4-5x^3+2x²+ 10x = (x+5)(2x-x³)
Step by Step explanation
Naming the coefficient of x² as "a" and the independent temine of the first parenthesis as "b", we got:
-x^4-5x^3+ ax^2 +10x=(x+b)(2x-x^3)
- x⁴-5x^3+ ax^2 +10x = 2x²- x⁴+2bx-bx³
-5x^3+ ax^2 +10x = -bx³+2x²+2bx
( Matching the exponents)
For x: 2b= 10; b=10/2.
b=5
For x²: a=2
For x³: -b=-5
b=5
Answer:
76
Step-by-step explanation:
Angle Formed by Two Chords= 1/2(sum of Intercepted Arcs)
94 = 1/2(x+112)
Multiply each side by 2
2*94 = x+112
188 = x+112
Subtract 112
188-112 =x
76 =x

Step-by-step explanation:
original cost 100*399 = 39,900
4 divided by 6 is 0.6666666667
Step-by-step explanation:
4x×8y
and x =2 and y=4
pit the values of x and y in above equation we get
4(2)×8(4)
now multiply
8×32
256
