Answer:
2 − 1.4h
Step-by-step explanation:
Step 1) Expand the terms in the parenthesis.
Step 2) Combine like terms
3 ⋅ 2 − 3 ⋅ 0.9h + 1.3h − 4
6 − 2.7h + 1.3h − 4
6 − 4 − 2.7h + 1.3h
2 − 1.4h
Answer:
The answer is 100 in
Step-by-step explanation:
The pythagorean theorm states that, for any right triangle where a and b are the legs and c is the hypotenuse, a^2 + b^2 = c^2. So, we can substitute and solve.
18^2 + 26^ 2 = c^2
324 + 676 = c^2
1000=c^2
Square root of 1000 = c
100.0=c
Hope this helps!
The answer is 1000 ft, 800 ft, 600 ft.
Let:
a - the longest side
b - the middle side
c - the shortest side
The <span>perimeter of a triangular plot of land is 2400 ft: P = 2400 ft
The perimeter of a triangle is P = a + b + c, thus a + b + c = 2400
</span><span>The longest feet (a) is 200 ft less than twice the shortest (c): a = 2c - 200
</span><span>The middle side (b) is 200 ft less than the longest side (a): b = a - 200
Now, we have the system of three equations:
</span>a + b + c = 2400
a = 2c - 200
b = a - 200
__________
Substitute a from the second equation into the third equation:
b = 2c - 200 - 200 = 2c - 400
__________
Substitute a and b into the first equation:
(2c - 200) + (2c - 400) + c = 2400
2c - 200 + 2c - 400 + c = 2400
2c + 2c + c - 200 - 400 = 2400
5c - 600 = 2400
5c = 2400 + 600
5c = 3000
c = 3000/5
c = 600 ft
_________
Now, use c and substitute into the second and third equation:
a = 2c - 200
a = 2 * 600 - 200
a = 1200 - 200
a = 1000 ft
___
b = a - 200
b = 1000 - 200
b = 800 ft
