Answer:
7cm
Step-by-step explanation:
Area = Length x width
A = 35
w= L - 2
L = w+ 2
Now it becomes
35 = ( w+2) x w
35 = w^2 + 2w
W^2 + 2w - 35 = 0
By Factorization we have
( w + 7)( w-5)
w = 5cm
Since L = w + 2, we have
L = 5 + 2
= 7cm
Answer:
C. 66 square units
Step-by-step explanation:
The area of the middle rectangle would by base × height, or y × h, or 6 × 6.
The area is 36.
The area for one triangle would 1/2 × base × height.
(But since there are two triangles to solve for, the 1/2 is not necessary, and we can just do base × height again.)
So, it would be x × h, or 5 × 6.
The area is 30.
Combine both areas to get the whole area of 66 units²
First, we have to add the fractions.
1/3 + 1/4 = 7/12
12 - 7 = 5

A Pythagorean triple consists of three positive integers a, b, and c, such that a2 + b2 = c2. Such a triple is commonly written (a, b, c), and a well-known example is (3, 4, 5). If (a, b, c) is a Pythagorean triple, then so is (ka, kb, kc) for any positive integer k.
