Answer:
75
Step-by-step explanation:
The answer is 75 because you have to cross mutiply:
1 3
25 x
<em>3 x 25 is 75</em>
Answer:
x=-2
Step-by-step explanation:
Becuz you are very dumb.
Answer:
C
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 1 • -56 = -56
Step-2 : Find two factors of -56 whose sum equals the coefficient of the middle term, which is -10 .
-56 + 1 = -55
-28 + 2 = -26
-14 + 4 = -10 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -14 and 4
x2 - 14x + 4x - 56
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-14)
Add up the last 2 terms, pulling out common factors :
4 • (x-14)
Step-5 : Add up the four terms of step 4 :
(x+4) • (x-14)
Which is the desired factorization
Equation at the end of step 1 :
(x + 4) • (x - 14) = 0
Answer:
B,C,D
Step-by-step explanation:
24ft =288 in A IS FALSE
2 miles = 10560 ft B IS TRUE
1/2 miles = 2640 ft C IS TRUE
0.5 miles = 880 Yds D IS TRUE
0.5 ft = 6 in E IS FALSE
Answer:
{2, 3, √13}
Step-by-step explanation:
In a right triangle, the sum of the squares of the two shorter sides equals the square of the third side (Pythagoras).
Let's check each set of sides in turn.
A. {2, 3, √13}
2² + 3² = 4 + 9 = 13
(√13)² = 13
This is a right triangle.
B. {5, 5, 2, √10}
This is a quadrilateral (four sides).
C. {5, 12, 15}
5² + 12² = 25 +144 = 169
15² = 225
This is not a right triangle.
