Answer:
So 2t%5E2%2B4t-30 completely factors to 2%28t%2B5%29%28t-3%29.
In other words, 2t%5E2%2B4t-30=2%28t%2B5%29%28t-3%29.
Note: you can check the answer by expanding 2%28t%2B5%29%28t-3%29 to get 2t%5E2%2B4t-30 or by graphing the original expression and the answer (the two graphs should be identical).

Solve for a.
4(a + 3)=12 + 4a
−1
no solution
all real numbers
−3
Final Answer: All Real Numbers
Steps/Reasons/Explanation:
Question: Solve for a. [tex]4(a + 3)=12 + 4a[/tex].
Step 1: Expand.
[tex]4a + 12 = 12 + 4a[/tex]
Step 2: Cancel [tex]4a[/tex] on both sides.
[tex]12 = 12[/tex]
Step 3: Since both sides equal, we would have infinitely many solutions.

Answer:
K = -2
Step-by-step explanation:
K represents the y-intercept, which is where the line crosses the y axis. We can see from the y = -4x -2, that -2 is the y-intercept, because in y = mx + b, b is the y -intercept.

a company dyes two sizes of rugs a small rug requires 8 hours for dyeing and a medium-sized rug requires 12 hours of dyeing the dryers have to make at least 22 guys ansld that must do it in less than 240 hours let x equal small rugs abd u equal medium rugs state a possible ordered pair solution for the system of inequalities justify mathematically using both inequalities
Answer:
C says 8x+12y, but D says 12x+8y, instead of 8x and 12y. The correct answer is C, I guess
Step-by-step explanation:
Let x=small rugs and y=medium rugs. It takes 8 hours to dye a small rug, so you would write 8x. It takes 12 hours to dye a small rug, so you would write 12y. Those two would need to be added together. The dyer needs to dye at least 22 rugs in 240 hours, so you would need a less than or = to sign.
I'm not sure which choice has the line beneath, indicating that the sign is a "less than or equal to" sign, but the answer is gonna be either C or D.
8x+12y≤240, or 12y+8x≤240

place an open circle on 4 and shade to the left
place a closed circle on 4 and shade to the right
place an open circle on -4 and shade to the left
place a closed circle on -4 and shade to the right
Answer: D
Step-by-step explanation:
-4 < -w
w > -4
Since it doesn't have an equal sign, its an open circle. Since its greater than -4, it is going to the right, so shade right.

Which unit is bigger?
millimeter
centimeter
meter
kilometer
Answer:
The answer is kilogram
Step-by-step explanation:
The answer is a kilogram because a kilogram is 1,000 times larger than one gram (so 1 kilogram = 1,000 grams). A centimeter is 100 times smaller than one meter (so 1 meter = 100 centimeters). A dekaliter is 10 times larger than one liter (so 1 dekaliter = 10 liters).
