Answer:
x²-2x-35
Step-by-step explanation:
(x-7)(x+5)
x²+5x-7x-35
x²-2x-35
Area of the triangle = 1/2 x base x height
Area of the triangle = 1/2 x 74 x 17
Area of the triangle = 629 ft²
Answer: 629 ft²
Answer:
Answer (d): (5, -2)
Step-by-step explanation:
Let's use the substitution method. Eliminate "x" in the second equation. Solving the first equation for x, we get x = -3y - 1. Subbing this for x in the second equation, we get:
2(-3y - 1) + 2y = 6, or, after multiplying as indicated,
-6y - 2 + 2y = 6.
Combining like terms,
-4y = 8, so that y = -2. If y = -2, then x is found from x = -3y - 1 (see above):
x = -3(-2) -1 = 5
Then the solution is (5, -2) (Answer d)
Answer:
C) 34 cm
Step-by-step explanation:
To calculate the perimeter we add all side lengths.
Answer:
0.4 is 40 percent of something because 100 percent is 1 x something. On the other hand, 0.12 is 12 percent of something because 0.12 x something will get you 12 percent of the value. Therefore, 0.4 is 40 percent of a thing while 0.12 is 12 percent of a thing and 0.4 is bigger than 0.12
