Answer:
5x= -15 I think
Step-by-step explanation:
You would have to solve the -6x+11=29 to find the value of x. To do so you would subtract the 11 from both sides leaving you with -6x=18. Then you divide that by -6 to find x. So x=-3. To find what 5x equals you would just plug in -3 as x and multiply 5(-3). Leaving you with -15.
Answer:
x=2
Step-by-step explanation:
let x be the edge length of the square removed at each corner;
Hence the area of the base is:
Using the quadratic equation formula, or completing the square, x, or length of a side of one of the squares is x=2 or x=58
#Given that x=58 is larger than 40cm, the side length is x=2
Answer:
14 months
Step-by-step explanation:
14x3=42
42+90= 132
Answer: Because we are trying to find the x-intercepts and the y-intercepts That would be (C)
Step-by-step explanation:
Self explanatory question, you set a quadratic equation to zero
For example: x 2 – 6 x = 16 equals to x 2 – 6 x – 16 = 0
Then, you would factor, that equals to (x – 8)( x + 2) = 0
(X-8)=0 (X+2)=0
X+2=0
-2 =-2
X=-2
X-8=0
+8 =+8
X=-8
To check you would simply plug in the values into the quadratic equation. They would both equal 16=16
