The expression that models the length of the second leg of the triangle is <u>2x - 3.</u>
<u><em>Recall</em></u>:
The area of a triangle = 
<em><u>Given</u></em>:
Area of triangle = 
Length of one of the legs = 3x + 1
Therefore, it means that multiplying both legs should give us:
To find the expression that models the other leg, divide by 3x + 1:
Therefore, the expression that models the length of the second leg of the triangle is <u>2x - 3.</u>

Because you can do the math of 4 times 5000 in your head *20,000* and then add what you got when you multiplied 4 × 384
OK. Let's build this thing brick by brick,
one step at a time:
The number. . . . . . . . . . . . . . . . . . . . . . . N
==> Three times the number . . . . . . . . 3N
6 times the number. . . . . . . . . . . . . . . . 6N
==> 28 more than 6 times the number . 6N + 28
You said the three times the number is the same
as 28 more than 6 times the number.
So I can write
3N = 6N + 28
That's the equation.
Subtract 3N from each side: 0 = 3N + 28
Now subtract 28 from each side: -28 = 3N
Now divide each side by 3 : N = - 28/3 .
That number is kind of weird, but it's the ONLY number
that behaves according to the description in the question.
Three times the number . . . . . -28
6 times the number . . . . . . . . . -56
-28 is 28 more than -56. yay!
Answer: 0.21
Step-by-step explanation:
2/10=0.2
1/100=0.01
0.2+0.01=0.21
Answer:
147.03 cm²
Step-by-step explanation:
Area of a parallelogram:
A = bh
A - area
b - base
h - height
From the figure,
Base = 16.9 cm
Height = 8.7 cm
A = (16.9)(8.7)
A = 147.03 cm²
