Answer:
Dimensions of rectangle are
Step-by-step explanation:
Area of rectangular knitted blanket =
We need to find the dimensions of blanket.
If we need to find the dimensions, we need to find the factors of area.
Factoring:
We will break the middle them -11x
- Adding 4x-15x we get -11x
- Multiplying 4x and -15x we get -60x^2 (Product of -6 and 10x^2)
Now, finding factors
So, factors of are
So, dimensions of rectangle are
Answer:
x = 4, y = 1
(4, 1)
Step-by-step explanation:
-2x - y = -9
5x -2y = 18
-2x - y = -9
+2x +2x
-y = 2x - 9
/-1 /-1
y = -2x + 9
5x -2y = 18
5x - 2(-2x + 9) = 18
5x + 4x - 18 = 18
9x - 18 = 18
+ 18 + 18
9x = 36
/9 /9
x = 4
Now, we solve for y:
-2(4) - y = -9
-8 - y = -9
+ 8 +8
-y = -1
/-1 /-1
y = 1
(x, y) -> (4, 1)
Hope this helps!
