Answer:
y = -4x - 31
Step-by-step explanation:
y + 3 = -4(x + 7)
y + 3 = -4x - 28
-3 -3
y = -4x - 31
Answer:
45/64 m²
Step-by-step explanation:
We are given the length and width of the tablecloth (breath = width).
- Length = 9/8 m
- Width = 5/8 m
We know that the formula for the area of a rectangle is A = L × W.
Assuming the tablecloth is in the shape of a rectangle (since the problem gives us length and width), we can substitute the length and width into the formula.
The area of the tablecloth is 45/64 m².
2L + 2w = 112 ---> L + w = 56 ---> w = 56- L
Area = L*w = L(56-L) = 735
56L - L^2 = 735
0 = L^2 - 56L + 735
0 = (L - 21)(L - 35)
THe dimensions of the rectangle are 35 x 21
Answer:
(x + 1)(x + 4)
Step-by-step explanation:
We want to factor x² + 5x +4 into two binomial factors. Note that 1*4 = 4 and that 1 + 4 = 5, so:
y = x² + 5x +4 = (x + 1)(x + 4)
