Answer:
Perform Multiplication
9+−6−6
Simplify
‐3
Step-by-step explanation:
First multiply -3 by -3 which equals 9. Then multiply 2 by -3 which equals -6. then put it together to get 9+-6-6. Finally do 9+-6=3-6=-3.
Answer: 10 inches.
Step-by-step explanation:
We have to solve a system of equations.
The formula to calculate a triangle area is A = (b.h)/2
where b is the base and h is the height. This will be our first equation.
Since the height is 4 inches greater than the base, the second equation will be: h = b+4
We replace h and the value of the area (70 square inches) in the first equation, and we solve it by using the cuadratic equation formula:
70 = (b . (b+4)) / 2
70 . 2 = b² + 4b
140 = b² +4b
0 = b² + 4b - 140
The roots of this polynomial are -14 and 10. Since a distance can't be negative, the length of the base is 10 inches.
Answer:
a = b/4
Step-by-step explanation:
Note that the LCD in this equation is 6. Rewriting 2a-b/6 = b/3 using this LCD, we get:
2a-b/6 = 2b/6
Multiplying all three terms by 6 eliminates the fractions:
12a - b = 2b
Combining like terms:
12a = 3b
3b
Solving this for a, we get a = ------------ = b/4
12
a = b/4
