<em>Answer:</em>
<em>The correct answer will be </em><em>"588 square centimeters"</em>
<em>Step-by-step explanation:</em>
<em>The answer would be 588 squared cm because the area of a triangle is 1/2(base*height). </em>
<em>and The base is 42 cm and the height is 28 cm. </em>
<em>588 square centimeters is the correct answer !</em>
In a triangle all the angles add up to 180 degrees.So we know that
(6x-1)+20+(x+14)= 180
6x+x+14-1+20=180
v v
7x + 13 + 20= 180
v
7x + 33=180
-33 -33
0 147
7x/7 = 147/7
x = 21
x=21
Then you substitute:
(6x-1) (x+14)
(6×21-1) (21+14)
v v
126-1 35
125 degrees / 35 degrees
125+35+20=180
Let's call the two numbers x and y. The first sentence, one is 6 less than twice another, translates to
We also know the sum of their squares:
So, we have the following system:
We can use the expression for x in terms of y from the first equation to turn the second equation into something involving y alone:
Expand the square:
Subtract 680 from both sides:
Using the quadratic equation
we find the two solutions
Since we know that both numbers are integer we can only accept the second solution. It yields the following x value:
No, because 32 is a composite number, and prime numbers cannot fit into composite numbers. Hope this helps.
