-3.5 * 2 = -7
-3.5 * 3n = 10.5n
So there is (-7 - 10.5n) -2.5n
Now combine like terms
10.5n - 2.5n = 8n
ANSWER = -7 + 8n
Answer: Simply - 5
Step-by-step explanation: Let's solve your equation step-by-step.
25+x2+10x=0
Step 1: Simplify both sides of the equation.
x2+10x+25=0
Step 2: Factor left side of equation.
(x+5)(x+5)=0
Step 3: Set factors equal to 0.
x+5=0 or x+5=0
x=−5
Hello from MrBillDoesMath!
Answer:
Choice B.
Discussion:
From the first step
324 x^6 y^ 8 =
2^2 * 3^4 * x^2 * x^4* y^8
so the fourth root of this is
2 ^(2/4)* 3^(4/4) x^(2/4)* x^(4/4)*y^(8/4) =
2^ (1/2) * 3^1 * x^(1/2) * x^(1)* y^ (2) =
(2x)^(1/2) * 3 * x * y^2 =
3 * x * y^2 * sqrt(2x) =
3 * x * y^2 * ( (2x)^2) ^ (1/4)) =
3 * x * y^2 * (4x^2) ^ (1/4)
which is choice B
Thank you,

Evaluate the expression 4(2x+y)-2y+z for x=-2, y=4 and z=-3

Before inserting the values of the variables, I recommend writing the equation in its simplest form.
First, use the distributive property and distribute 4:-
8x+4y-2y+z
Simplifying,
8x+2y+z
Now that the expression is in its simplest form, we can substitute the variables and simplify the expression.
First, write -2 in lieu of x:-
8(-2)+2y+z
-16+2y+z
Now, write 4 in lieu of y:-
-16+2(4)+z
-16+8+z
-8+z
Final step:-
write -3 in lieu of z:-
-8+(-3)
-8-3
-11
