Answer:
The expression 5 × 2 = 10 means:
- 10 is 5 times as many as 2.
Step-by-step explanation:
Given the expression
From the expression, it is clear that we can determine that when we multiply 2 by 5 to get 10.
In other words, we can determine the value 10 by:
It means 10 is 5 times as many as 2.
Therefore, the expression 5 × 2 = 10 means:
- 10 is 5 times as many as 2.
Answer: 35.675
Step-by-step explanation:
10.465−(−25.21)
The opposite of −25.21 is 25.21.
10.465+25.21
Add 10.465 and 25.21 to get 35.675.
35.675
Answer:
Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
Exact Form:
x = − 70 ± √4210/30
Decimal Form:
x = −0.03
Step-by-step explanation:
5x(6x+28)=−23
Step 1: Simplify both sides of the equation.
30x2+140x=−23
Step 2: Subtract -23 from both sides.
30x2+140x−(−23)=−23−(−23)
30x2+140x+23=0
Step 3: Use quadratic formula with a=30, b=140, c=23.
x=−b±√b2−4ac/2a
x=−(140)±√(140)2−4(30)(23)/2(30)
x=−140±√16840/60
x=−7/3+1/30√4210 or x=−7/3+−1/30√4210
