Since the area of a rectangle is base times height.
Combining the two areas, we get
A(total) = A1 + A2 = (20*5) + (12*3) = 136 square yard
The answer is A.
Answer:
The answer is y=1.5x
Step-by-step explanation:
When you do 4 x 3, that gets you 12, but on the table it says 6. You can get rid of that option.
When you do 4+2, it gets you 6. But when you do 6+2, it gets you 8. On the table it says 9. You can get rid of that option.
When you do 4 x 2, you get 8, but the table says 9. You can get rid of that option.
That then only leaves you with 1.5, which works with all of the values.
Answer:
- (x -3)(x+3)(2x +1)
- (x -1)(x +1)(x +3)
- (2x -1)(2x +1)(x -4)
Step-by-step explanation:
A) 2x³ +x² -18x -9 = x²(2x +1) -9(2x +1) = (x² -9)(2x +1) = (x -3)(x+3)(2x +1)
__
B) x³ +3x² -x -3 = x²(x +3) -1(x +3) = (x² -1)(x +3) = (x -1)(x +1)(x +3)
__
C) 4x³ -16x² -x +4 = 4x²(x -4) -1(x -4) = (4x² -1)(x -4) = (2x -1)(2x +1)(x -4)
_____
In each case, the third-level factoring mentioned in step 4 is the factoring of the difference of squares: a² -b² = (a -b)(a +b).
_____
The step-by-step is exactly what you need to do. It is simply a matter of following those instructions. You do have to be able to recognize the common factors of a pair of terms. That will be the GCF of the numbers and the least powers of the common variables.
Answer:
4.2
Step-by-step explanation:
First I did 54 divided by 3 which is 18. Then I found the square root of 18.
