Answer:
c. a: 4
b: 12
c: 9
4x² +12x+9=0
(2x+3)(2x+3)= 0
(2x+3)²=0 {square root both sides}
2x+3=0
2x=-3
x= -3/2
Answer:
1.89
Solution:
We have -44x - 86 = -3
First, we move the non x terms to the RHS of the equation. To do this, we add 86 to both sides.
Note: if a = b, then a + c = b + c
Therefore, -44x - 86 + 86 = -3 + 86
or, -44x = 83
Next, divide both sides by -44, which is the coefficent of x
Note: if a = b, then a ÷ c = b ÷ c
-44x
-44
=
83
-44
or, x = -1.89
Explaination:
This is right I guess
Choice 1
Choice 1 and 3 shows parallel, choice 2 and 4 shows perpendicular. So cross out choices 2 and 4. We’re left with choices 1 and 3. I would go with choice 1 since choice 3 shows RAY A is parallel to RAY B, which isn’t true, they’re not parallel.
I’m not for sure but if I had to guess I would say 115
The value of the expression is one eight
<h3>How to solve the expression?</h3>
The expression is given as:
negative one fifth times the quantity 4 minus 14 times the quantity one fourth squared end quantity
Rewrite properly as:
-1/5 * (4 - 14) * (1/4)^2
Evaluate the difference
-1/5 * (-10) * (1/4)^2
Evaluate the exponent
-1/5 * (-10) * 1/16
This gives
2 * 1/16
Further, evaluate
1/8
Hence, the value of the expression is one eight
