If the area of triangle ABD is 12 square units, what is the area of Rectangle ABCD?
The length of a rectangle is 1 less than twice the width. Write the equation that could represent the area of the rectangle in terms of the width
Answer:
(W2-1)xW
Step-by-step explanation:
The beginning of the equation represents the length as the question states it is one less than twice the width. Because you need to multiply width and length to get area, you place the length equation and parentheses and multiply the answer to the equation by the width :) Hope this helps!
Based on the problem statement, we have a word problem before us, that is solving for the area of a rectangle with given sides.
Area = 2y^2-y
Given data
Let the Length of the rectangle be x
and let the width be y
From the statement "The length of a rectangle is 1 less than twice the width"
the length can we re-written as
x = 2y-1
We know that the area of a rectangle is
Area = Length*Width
Area = (2y-1 )* y
Area = 2y^2-y
hence the expression for the area is given as 2y^2-y

What is the value of x?
Answer:
D. 75
Step-by-step explanation:
A triangle’s angles equal 180 degrees according to the Triangle Sum Theroem. So, 180-70-35=75.
PLZ MARK BRAINLIEST!!!
Answer:
D. 75 degrees
Step-by-step explanation:
The three angles of a triangle have to add up to be 180 degrees. 70+35= 105, and 180-105= 75. Therefore, the third angle must be 75 degrees in order for it to be a proper triangle.

Jessie rode his bike for 13 hours last month. He rode 7 hours the first week of
the month. He rode the same number of hours each week for the remaining 3
weeks. Which equation or inequality best represents the number of hours. h.
Jesse rode per week for the last three?
Answer:
13=7+3h
Step-by-step explanation:
13 is all together, 7 for first week, and the other 3 have the same amount.
so you can say 13= 7 for the first week+ 3 of the same amount of hour which can be written as 3h.

Evaluate f(x)=x+3for f(-2)
Answer:
f(-2) = 1.
Step-by-step explanation:
If we are solving for f(-2), we will simply need to substitute in '-2' for 'x'. This gives us:
f(-2) = -2 + 3
f(-2) = 1.
Evaluate f(x) = x + 3 for f(-2)
Given: x = -2
Plug in -2 for x in the equation:
f(x) = x + 3
f(-2) = (-2) + 3
f(-2) = 3 - 2
f(-2) = 1
f(-2) = 1
1 is your answer.

On a coordinate plane, a curve approaches y = negative 4 in quadrant 3 and then increases exponentially in quadrant 1. It crosses the y-axis at (0, negative 3).
Answer:
y = e^x - 4
Step-by-step explanation:
The missing options are
y = ln x - 3
y = ln x - 4
y = e^x - 3
y = e^x - 4
The function is defined in quadrant 3 and increases exponentially, then it is not a logarithm.
f(x) crosses the y-axis at (0, -3). Replacing x = 0 the last option, we get:
y = e^0 - 4 = 1 - 4 = -3
Answer:
y = e^x - 4

How many points are 3 units from the y-axis and 1 unit from (4,1)?
Intuitively we're being asked how many points on the radius 1 circle centered at (4,1) are three units from the y axis. The answer is pretty obviously
Answer: One point
We'll work it out the usual way.
Let's give coordinates (x,y) to a point 3 units from the y axis and 1 unit from (4,1).
The x coordinate tells us how far we are from the y axis. 3 units from the y axis means
|x| = 3
x = ±3
One unit from (4,1) means
(x - 4)² + (y - 1)² = 1²
Let's try x=-3
(-7)² + (y - 1)² = 1
(y - 1)² = -48
No solution there
Let's try x=3
(3 - 4)² + (y - 1)² = 1
(-1)² + (y - 1)² = 1
(y - 1)² = 0
y - 1 = 0
y = 1
So (3,1) is the only point 3 units from the y axis and 1 unit from (4,1).
That verifies our answer above.

Find the distance between the points (15, -11) and (15, -19).
Answer: 8
Step-by-step explanation:
Distance formula: square root x2-x1 squared + y2-y1 squared.
15-15=0
0 squared=0
-19- -11= -8
-8 squared=64
Square root 64= 8
Answer:
8 units
Step-by-step explanation:
the easiest way to work out the distance for these two points is to plot them on a linear graph. as they are in line (because they're both inline with 15 on the x-axis), you just have to count the numbers between -11 and -19. in this case there are 8 units between the two points.

What is the finance charge?A finance charge is any fee representing the cost of credit, or the cost of borrowing. It is interest accrued on, and fees charged for, some forms of credit. It includes not only interest but other charges as well, such as financial transaction fees.
Finance charge = {(250x12) +435}- 2900

In the figure polygon ABCD is transformed to create polygon A’B’C’D’. This transformation is a ____ by a factor of ____.
Answer:
In the figure polygon ABCD is transformed to create polygon A’B’C’D’. This transformation is a horizontal stretch by a factor of 2.
Step-by-step explanation:
Dilation is a combination of vertical and horizontal stretch. In this case, the stretch os only horizontally applied.
We can see in the picture that the measure of figure ABCD in the x-axis is 2 units long and of Figure A'B'C'D' is 4 units long (double than ABCD). Then the stretch factor is 2.
