This looks one hundred percent correct to me and to check your answer you can plug in the answer you find to the first equation
17=37+4f
17=37+4(-5)
17=37-20
17=17
great job!!
23 m, 17 m, 14 m
Cuz the length of a side must be bigger than the difference of the other two
In my opinion the answer is <span>m2 – 100 = –99
proof
</span>m2 – 100 =<span>(m – 10)(m + 10)
for eg. m=1, </span>(-9)(11)= <span>–99</span>
The difference in ' x ' (left or right) between D and F is 5 units.
The difference in ' y ' (up or down) between D and F is 2 units.
The straight-line distance between them is
√ (5² + 2²)
= √ (25 + 4)
= √ (29)
= 5.3851.....
or 5.4 (rounded to the nearest tenth)
