4*5+w is wrong!

the correct answer:
4*(5+w)

you must add brackets to make sure the sum of 5 and w is being multiplied

BEDMAS / PEMDAS plays a role in this

(I would appreciate a brainliest)

The tree in greg's backyard is 8 meters high. How high is it in centimeters
Elina [12.6K]
1 meter is 100 centimeter, as "centi" means 1 hundredth:

So 100 centimeter means 100-"1 hundredth" meters, which is 1 meter.


In short, since 1 meter is 100 centimeters, 8 meters are 800 centimeters.


Answer: 800 cm

The length of the radius of a bicycle wheel is 14 inches. Which of the following is closest to the circumference of the wheel? A
tatuchka [14]

Answer:

C. 88 in.

Step-by-step explanation:

This is because the equation for the circumference of a circle is pi times diameter. To get the diameter, multiply the radius by 2. Then do 28*3.14 to get the circumference of the circle then round your answer to get the nearest whole number which is 88 in.

X^2+17x+50=0 to the nearest tenth.
goldenfox [79]

Answer: 2.1      Find the Vertex of   y = x2-17x-50

Parabolas have a highest or a lowest point called the Vertex .   Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) .   We know this even before plotting  "y"  because the coefficient of the first term, 1 , is positive (greater than zero).  

Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two  x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.  

Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.  

For any parabola,Ax2+Bx+C,the  x -coordinate of the vertex is given by  -B/(2A) . In our case the  x  coordinate is   8.5000  

Plugging into the parabola formula   8.5000  for  x  we can calculate the  y -coordinate :  

 y = 1.0 * 8.50 * 8.50 - 17.0 * 8.50 - 50.0

or   y = -122.250

Four times the sum of a number and 15 is at least 120. Let x represent the number. Find all possible values for x.
lorasvet [3.4K]
Four times the sum of a number and 15 is at least 120
Let ‘x’ represent the number.
 "The sum of a number and 15"
This can be written mathematically as x + 15
 Given that 4 times this sum is at least 120,
This means that 4 times the sum is greater than or equal to 120
This can be written mathematically as 4(x + 15) >= 120
 Solving for x
 4(x + 15) >= 120
4x + 60 >= 120
4x >= 120 – 60
4x >= 60
x >= 60/4
x >= 15
 x is greater than or equal to 15 <span>
