Answer:
3
Step-by-step explanation:
Since we already know c, so we need to find b.
c² = a² + b²
5² = 4² + b²
b² = 5² - 4²
b² = 25 - 16
b² = 9
b = 3
Answer:
$106.00
Step-by-step explanation:
origional amount = x
x + 26 + x + 26 = 264
2x + 52 = 264
2x = 264 - 52
2x = 212
x = 212/2
= 106
Hope this helps you! Have an amazing day :)
Answer:138
Step-by-step explanation:
First plug in the c and d values into the expression:
6(5)^2-5(4)+8
Remember PEMDAS, so you do 5^2 first getting you 25.
6(25)-5(4)+8
Continue with PEMDAS and multiply -5 and 4, and that gets you -20.
150-20+8
Now you simplify the expression to get: 138.
Answer:
B
Step-by-step explanation:
Inequalities of the type | x | ≤ a, have solution of the form
- a ≤ x ≤ a , so
| x | ≤ 4
- 4 ≤ x ≤ 4
The values of x are between - 4 and + 4, but can equal - 4 and 4 since the symbol is ' less than or equal to '
This is indicated on a number line by solid circles, where not equal to are denoted by open circles.
Thus the solution is Graph B
