Answer:
Step-by-step explanation:
F: 4x*2x = 8x^2
O: (4x)*3 = 12x
I : 8*2x = 16x
L: 8*3 = 24
End of First step
========================
Just in case you want the answer
8x^2 + 28x + 24
And to take out the common factor
4(2x^2 + 7x + 6)
Answer:
(4x + 8) (2x+3)
FOIL
First- (4x)(2x)= 8x2
Outer- (4x) (+3)= +12x
Inner- (8) (2x)=16x
Last- (8) (+3)=+24
The model of the shaded region is 0.80. And if 8 square boxes were shaded, then Koran's model was right.
A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Koran showed 0.08 with the model.
In the model,
there are ten columns and ten rows.
That means, 100 square boxes.
And the shaded region have 8 columns and 10 rows.
That means, 80 square boxes.
Koran showed the percentage of shaded region of the model.
That is, 0.08 is 8%.
So let n be the percentage of shaded region.
So, 80 =n x 100/ 100
n = 80%
And 80% in decimal is 0.80.
And if Koran wants 0.08.
That means, 8% of shaded region.
So 8% 0f 100 is 8 square boxes.
Therefore, if 8 square boxes were shaded, then Koran's model was right.
