Answer:
6 cm and 8 cm
Step-by-step explanation:
Use Pythagorean theorem:
c² = a² + b²
10² = x² + (x+2)²
100 = x² + x² + 4x + 4
0 = 2x² + 4x − 96
0 = x² + 2x − 48
0 = (x − 6) (x + 8)
x = 6 or -8
x must be positive, so x = 6. Which means x+2 = 8.
Answer:
D
Step-by-step explanation:
We need to find 2 roots of the quadratic function given and find the greater of the two roots.
We factorize the quadratic and find the two solutions first:
So,
x = 1
and
x= 5
Out of the two, x = 5 is the greater root.
D is the correct answer.
Answer:
- 10
- 15ab
Step-by-step explanation:
1. The square of the binomial is ...
(* -2m)^2 = *^2 -4m* +4m^2
Matching terms, you find ...
*^2 = 100
-4m* = -40
Both of these equations tell you the value of * is 10.
___
2. Same deal. Multiply ou the square and see what you have.
(3a +2.5b)^2 = 9a^2 +15ab +6.25b^2
The term missing on the right side of the given equation is 15ab.
