what is the surface area
Answer:
The surface area of the rectangular prism is 748 ft2.
Step-by-step explanation:
formula for surface area: A=2(wl+hl+hw)
A=2(wl+hl+hw)=2(5x16+14x16+14x5)=748
Answer:
748 ft²
Step-by-step explanation:
For the surface area, you need to add up the area of all sides, six in this example, but it can be simplified into three by multiplying some of them by two as its presumed a rectangle
x1 = 5*14*2 = 140
x2 = 16*14*2 = 448
x3 =16*5*2 = 160
You find the sum of these; 140 + 160 + 448 = 300 + 448 = 748
Complete the square
to find the vertex
of this parabola.
x?+8y+2x - 23=0
Answer:
The vertex of the parabola is;
([-1], [3])
Step-by-step explanation:
The given quadratic equation is presented as follows;
x² + 8·y + 2·x - 23 = 0
The equation of the parabola in vertex form is presented as follows;
y = a·(x - h)² + k
Where;
(h, k) = The vertex of the parabola
Therefore, we have;
x² + 8·y + 2·x - 23 = 0
8·y = -x² - 2·x + 23
y = 1/8·(-x² - 2·x + 23)
y = -1/8·(x² + 2·x - 23)
y = -1/8·(x² + 2·x + 1 - 23 - 1) = -1/8·(x² + 2·x + 1 - 24)
y = -1/8·((x + 1)² - 24) = -1/8·(x + 1)² + 3
Therefore, the equation of the parabola in vertex form is y = -1/8·(x + 1)² + 3
Comparing with y = a·(x - h)² + k, we have;
a = -1/8, h = -1, and k = 3
Therefore, the vertex of the parabola, (h, k) = (-1, 3).

2x+4y is the equivalent expression of x+x+4y.
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is x + x + 4y
x plus x plus four times of y.
In the given expression x and y are two variables.
Equivalent expressions are expressions whose value will remain same after simplifying or solving.
We need to add x variable terms once and then with y term
x + x + 4y
2x+4y
Hence, 2x+4y is the equivalent expression of x+x+4y.

City y is 10 miles north of city x city z is 24 miles east of city x how long is the straight roads connecting cities y and z?
Answer:
26 miles
Step-by-step explanation:
Using Pythagoras rule :
d = straight road connecting city Y and Z :
d = sqrt(xy² + xz²)
d = sqrt(10² + 24²)
d = sqrt(100 + 576)
d = sqrt(676)
d = 26 miles

When would you use a pictograph? to compare change over time if the data is numerical to save space for a large set of data if the data is categorical
Answer:
to save space for a large set of data
if the data is categorical
Step-by-step explanation:
The pictograph is used if the data is categorical
What is a pictograph?A pictograph is a type of graph that uses pictures or symbols to represent data. It is best used when the data is categorical or non-numerical. For example, a pictograph can be used to show the favorite types of fruits of a group of people or the most popular colors of a group of cars.
Pictographs are useful for presenting data in a visually appealing way that is easy to understand, especially for younger or less experienced readers. They are less useful for comparing change over time or for presenting large sets of numerical data, as they can become cluttered and difficult to read.
Given data ,
Let the pictograph be represented as A
Now , pictographs are less useful for comparing change over time or for presenting large sets of numerical data, as they can become cluttered and difficult to read.
For example, if you want to show how the population of a city has changed over the years, a line graph or a bar graph would be a better choice than a pictograph
Hence , pictographs are useful if there is categorical data

Step-by-step explanation:
Answer:
55 °
Here's the way i got my answer :
Complementary angles are two angles that have a sum of 90° ,therefore 35° + X = 90°
X=55° .
to get ∠DBF
180° - 90° = 90 °
to get ∠EBF
∠CBD + ∠DBE + ∠EBF = 180°
35° + 90° + ∠EBF = 180°
∠EBF = 55°
