In any rectangle, the area is given by the product of the width and the length.
Since in this case both dimensions are represented by the correspondent function, you need to multiply the function:
Answer:
a exponent 2-b exponent 2
ab
Answer:
perimeter of rectangle= 2(4+X)
32=8+2x
32-8=2x
26=2x
26/2=X
14=X
perimeter of triangle=3×sides
20=3x
20/3=X
6.66=x
Answer:
No. Remember, a right angle must have a 90 degree angle. We can find the lengths with the Pythagorean Theorem.
Step-by-step explanation:
Given the length 7, 10, and 12, we can assume that 12 is the hypotenuse (it is the longest length).
- we can use 7 and 10 interchangeably.
Fill in the equation,
where c = 12, and a or b = 7 or 10.
To indicate if the given lengths would form a right angle, we can only input 7 or 10, not both.
Therefore, or
==> 49 + b^2 = 144 ==> <u>b= </u><u> ==> </u><u>9.746</u>
b= 9.7, not 10.
==> 100 + b^2 = 144 ==> <u>b = </u><u> ==> </u><u>6.633 </u>
b= 6.6, not 7.
Therefore, the lengths 7, 10, and 12, does NOT make a right triangle.
