Answer:
$18
Step-by-step explanation:
small -$3
large - $15
3+15=18
Answer: The equation is $3 + ($3 x 5)
Step-by-step explanation:
You add $3 to 3 multiplied by 5 to get the cost of the second car which will then give you the cost of both cars. Then you simplify and get $3 + $15 which gives us the answer $18. So the cost of both the cars is $18.
Answer: No
Explanation: In the first problem, 2 is a base and 7 is an exponent.
The 7 that is raised up means we multiply our base together seven times.
This means the same thing as 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 or 128.
On the other hand, 2 × 7 is 14.
It can also be thought of as 2 + 2 + 2 + 2 + 2 + 2 + 2 or 14.
Answer:
No, 2^7 is not the same thing as 2 x 7
Step-by-step explanation:
When you are doing 2 x 7 you multiply 7 by 2. For 2^7, you multiply 2 by 2 7 times.
2 x 7 = 2 x 7
2^7 = 2 x 2 x 2 x 2 x 2 x 2 x 2
Answer: 12
Step-by-step explanation:
Simplify the radical by breaking the radicand up into a product of known factors.
Answer:
(8+2) and (9+1) is the most fastest adding pair.
Step-by-step explanation:
It is easy to add zero digit number here it will be
We can club the two number or we can club two pair so as to form 10 in each of the pair
It will be (8+2) which gives 10
And (9+1) which gives 10
And it will very easy and fast to add 10 + 10
Rather than any other pair.
3x^2+x-4=0
Solve by factoring or using the quadratic formula
