Find the smallest zero for the function h(x)=4x^2-8x-60.

ankoles [38]

H(x) = 4x² - 8x - 60
0 = 4x² - 8x - 60
  0 = 4(x²) - 4(2x) - 4(15)
  0 = 4(x² - 2x - 15)
4 4
0 = x² - 2x - 15
0 = x² - 5x + 3x - 15
0 = x(x) - x(5) + 3(x) - 3(5)
0 = x(x - 5) + 3(x - 5)
0 = (x + 3)(x - 5)
0 = x + 3 or 0 = x - 5
- 3 - 3 + 5 + 5
3 = x    or    5 = x

What is the correct answer to 20÷2(5+5)?

poizon [28]

Answer:

To answer the question above, we need to know about the rules of mixed count operation. In mixed count operation, we can find plus [+], minus [-], divided [:], multiplication [x] and parenthesis [(...)]. For example, if the operation is: 7 x 5 + 3 - (4 x 3) : 6 = ...

first, we must finish the operation inside the parenthesis symbol, which is (4 x 3), the result is 12

second, we must finish the operation with the multiplication or divided symbol but, if both exist we must finish the far left-side first. for this example is to finish "7 x 5 = 35" first, then finish the next operation with divided symbol "(4 x 3) : 6 = 12 : 6 = 2"

for the last, we finish the operation with plus or minus symbol, but if both exist then we must finish the far left-side first. For this example is to finish "35 + 3 = 38", then finish the next operation which is "38 - 2 = 36".

there are the rules of mixed count operations, to make it clear we finish the example operation step by step

7 x 5 + 3 - (4 x 3) : 6 = ...

7 x 5 + 3 - 12 : 6 = ...

35 + 3 - 12 : 6 = ....

35 + 3 - 2 = ...

38 - 2 = 36.

now the answer to the mixed count operation above 20 : 2 (5 + 5) = ...

20 : 2 x (5 + 5) = ...

20 : 2 x 10 = ...

10 x 10 = 100

the answer of the operation is 100

Please help !!! can someone explain?

kari74 [83]

Given:

Total cites are $1\dfrac{1}{2}$ inches apart on the map.

Scale of the map is $\dfrac{1}{2}\text{ inch }=40\text{ miles}$

To find:

The actual distance between two cities.

Solution:

Distance between two cities on map = $1\dfrac{1}{2}$ inches

= $\dfrac{1(2)+1}{2}$ inches

= $\dfrac{3}{2}$ inches

We have,

$\dfrac{1}{2}\text{ inch }=40\text{ miles}$

Multiply both sides by 3.

$\dfrac{3}{2}\text{ inch }=3\times 40\text{ miles}$

$\dfrac{3}{2}\text{ inch }=120\text{ miles}$

So, the actual distance between two cities is 120 miles.

Therefore, the correct option is D.
