Area of parallelogram = base × height
Area = 4 × 1
= 4cm^2
Answer:
20
Step-by-step explanation:
24.80-6.80=$18 that's what Britta spent on equal number of carrots and apples because $6.80 was spent on extra carrots only.
18/ .90=20 that means she got 20 apples and 20 carrots before she added $6.80 to buy some extra carrots
Thus, the number of apples Britta bought = 20
Answer:
the percentage is 12%
Step-by-step explanation:
Given that
The 12 students picked up the vanilla cupcake
And, 88 students picked up the chocolate cupcake
We need to find out the percentage of the students picked up a vanilla cupcake
So, the percenatge is
= (12) ÷ (12 + 88) × 100
= 12 ÷ 100 × 100
= 12%
Hence, the percentage is 12%
Answer:
x^2 -x -2 = (x -2)(x +1)
Step-by-step explanation:
To factor x^2 -x -2, you look for factors of -2 that have a sum of -1:
-2 = (-1)(2) = (1)(-2) . . . . . the latter pair has a sum of -1
Then these are the constants in the binomial factors:
x^2 -x -2 = (x +1)(x -2)

<em>Comment on the question</em>
The fact that x^2 +3x -4 is modeled with algebra tiles seems to be irrelevant to the question that is actually asked.
