Answer:
area = 44 cm²
Step-by-step explanation:
rectangle area = bh = 8 x 4 = 32 cm²
triangle height² = 5² - 4³ = 25 - 16 = 9
triangle height = 3
triangle area = 1/2bh = 1/2(8)(3) = 12 cm²
32 cm² + 12 cm² = 44 cm²
area = 44 cm²
Answer:
Multiply the first equation by 4.
Step-by-step explanation:
4(x+y=3) which gives
4x+4y=12
and
4x-y=7
Then subtract the two equations and the x variable will be eliminated.

Answer:
Step-by-step explanation:
5²+10²=25+100=125
13²=169
so 5²+10²≠13²
so it is not a right angled triangle.
