A/b ÷ d/c
a/b * c/d
4x/ x² + 5x -6 * x² + 7x + 6/ x² - 11x + 28 factor
4x/ (x+6)(x-1) * (x+6)(x+1)/ (x-7)(x-4) (x+6) cancels out
4x (x+1) / (x-1)(x-7)(x-4)
Answer:
The volume of the concrete needed to make the block is 5054 ft³
Step-by-step explanation:
The question relate to the calculation of the volume of a shape
The dimensions of the block are;
The depth of the block, d = 19 ft.
The width of the block, w = 19 ft.
The length of the block, l = 14 ft.
The volume of a cube, V = Length, l × Width, w × Depth, d
Therefore, the volume, 'V' of a cubic block is given as follows;
V = l × w × d = 14 ft. × 19 ft. × 19 ft. = 5054 ft.³
The volume of the concrete needed to make the block = The volume of the block, V = 5054 ft³.
I think the answer is r = 5/12
there's a grid of squares with 12 rows and in each row there are 15 squares
from this grid she colours 8 squares from each row for 5 rows blue.
the rest of the squares she colours red
so first we have to find how many squares are there in the grid in total
so if each row has 15 squares
then 12 rows have - 15 x 12 = 180 squares
blue coloured squares
she colours 8 rows of 5 squares
so if 1 row has - 5 squares
then 8 rows have - 5 x 8 = 40 squares
from 180 squares, she colours 40 squares blue and the rest red colour
therefore the squares she colours red are
red squares = 180 - 40 = 140 squares
she colours 140 squares red

ab i think that is the answer <span />
