169=13*13
13-7=6
old area was 6*6=36
then, the lenght is 6
Answer:
i don't know the rule but when subtracted there is a number3 difference
umm 26 i'm not sure
Step-by-step explanation:
Answer:
l = 10 feet, m = 30 feet and n = 25 feet
Step-by-step explanation:
The attached figure shows a triangle in which three sides as as follows :
, m and 
Perimeter of triangle is 65 feet.
Perimeter = sum of all sides
put the value of n
Now put the value of l
⇒ 
And
Hence, l = 10 feet, m = 30 feet and n = 25 feet.
Answer:
Step 3: He should have divided both sides by −7
Step-by-step explanation:
Incorrect calculation
−7x + 25 = 48
Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23
Step 3: negative seven times x over seven = twenty-three over seven
-7*x/7 = 23/7
-7x/7 = 23/7
Step 4: x = twenty-three over seven
Correct calculation
−7x + 25 = 48
Step 1: −7x + 25 − 25 = 48 − 25 Step 2: −7x = 23
Step 3: negative seven times x over seven = twenty-three over seven
-7*x/-7 = 23/-7
-7x/-7 = 23/-7
Step 4: x = twenty-three over negative seven
x = -23/7
Im pretty sure it is D. The domain is all real numbers, so by plugging in any number of your choice, a point will be plotted.
