Answer:
C
Step-by-step explanation:
x^3+4x^2-9x-36=0
or x²(x+4)-9(x+4)=0
or (x+4)(x²-9)=0
or (x+4)(x+3)(x-3)=0
x=-4,-3 or 3
Answer:
x = -1 and y = 18
Step-by-step explanation:
Given the system of equations
y + 8x = 10... 1
2y - 4x = 40 ... 2
From 1; y = 10-8x
Substitute into 2;
2(10-8x) - 4x = 40
20 - 16x - 4x = 40
20 - 20x = 40
-20x = 40 - 20
-20x = 20
x = -1
Recall that y = 10-8x
y = 10 - 8(-1)
y = 10 + 8
y = 18
therefore your answer is x = -1 and y = 18
Answer:
9/12 and 6/8
Step-by-step explanation:
We are given expression: 
.
Square root in exponent form is power 
.
Therefore, 
.
Now, replacing square root of 16 by 
in original expression we are given, we get
.
Therefore,
<h3>
= 16 in simplest form. By the Power of Power rule,
. So,
must equal
in radical form.</h3>
