a. –96
b. –9.6
c. 9.6
d. 96

Answers

Answer 1

Answer: -8 * 1.2 = -9.6
first see if the the two numbers have the same signs or different signs, since this equation has different signs the answer will be negative.So now the last thing you have to do is multiply 8 by 1.2 which is 9.6 .now all you do is add the negative sign so now your answer is -9.6

Answer 2

Answer: -8•1.2=-9.6Awnser=B

4(a-1) -5 =3a + 7

Answers

Distributive property says 4 * a and 4 * -1 so 4a - 4 - 5 = 3a + 7
Now do the simple subtraction
-4 - 5 = -9
Then add 9 and subtract 3a Remember: Always do the opposite operation to both
sides. So you have a = 16

$4\cdot(a-1)-5=3a+7\n\n4\cdot a-4\cdot1-5=3a+7\n\n4a-4-5=3a+7\n\n4a-9=3a+7\ \ \ /+9\n\n4a-9+9=3a+7+9\n\n4a=3a+16\ \ \ \ /-3a\n\n4a-3a=3a-3a+16\n\na=16$

What is the simplified form of x minus 5 over x squared minus 3x minus 10 ⋅ x plus 4 over x squared plus x minus 12? (6 points)

Answers

Answer: Our simplified form will be

$(1)/((x+2)(x-3))$

Step-by-step explanation:

Since we have given that

$(x-5)/(x^2-3x-10)* (x+4)/(x^2+x-12)$

So, first we split the middle term of the denominator ,

$x^2-3x-10=0\n\n=x^2-5x+2x-10\n\n=x(x-5)+2(x-5)\n\n=(x-5)(x+2)$

Similarly,

$x^2+x-12=0\n\nx^2+4x-3x-12=0\n\nx(x+4)-3(x+4)=0\n\n(x+4)(x-3)=0$

Now, we put in our expression above:

$(x-5)/((x-5)(x+2))* (x+4)/((x-3)(x+4))\n\n=(1)/(x+2)* (1)/(x-3)\n\n=(1)/((x+2)(x-3))$

Hence, our simplified form will be

$(1)/((x+2)(x-3))$

Step 1 is to factor everything!

After factoring you will get:

x-5 over (x+2)(x+5) times x+4 over (x-3)(x+4)

Step 2 is to remove the duplicate factors!
Remove x+4 and x+5

x-5 over (x+2)(x-5) times 1 over x-3 = 1 over x+2 times 1 over x-3

Step 3 is to multiply the numerators and the denominators.

End result is 1 over (x+2)(x-3)
