Answer:
73 cm (Estimated)
Step-by-step explanation:
Let's use hero's formula to solve this.
=> 1/2(14 + 11 + 18) = S
=> 1/2(43) = S
=> S = 21.5
√s(s - a)(s - b)(s - c)
=> √21.5(21.5 - 14)(21.5 - 11)(21.5 - 18)
=> √21.5 x 7.5 x 9.5 x 3.5
=> 73.2226911551 = Area of triangle
=> 73 cm² (Estimated)

David wants to purchase some pens. The pens he likes cost $2 each, not including tax. This is represented by the graph below.
Notice triangle BAC.
Notice triangle BDE.
Explain how the triangles demonstrate that the rate of change is consistent for number of pens purchased and the cost.
The rate of change is always the same for a straight line no matter the points used.
The equation of a straight line is given by:
y = mx + b;
where y, x are variables, m is the rate of change and b is the y intercept.
In triangle BAC:
Rate of change = change in y(cost) / change in x(pens) = (6 - 0) / (3 - 0) = 2
In triangle BDE:
Rate of change = change in y(cost) / change in x(pens) = (8 - 0) / (4 - 0) = 2
The rate of change is always the same for a straight line no matter the points used.

2(7x-34) = 22
Find X
Brainliest
Answer:
x = 6.428
Step-by-step explanation:
2(7x-34) = 22
Distribution:
2 times 7x = 14x
2 times -34 = -68
Your equation is now:
14x - 68 = 22
Add 68 on both sides to leave 14x alone
68+22 = 90
You are left with this equation:
14x = 90
Divide by 14 to isolate the x
90/14
x = 6.428 (approximately)
Answer:
The value of x is 45/7.Work:
2(7x - 34) = 22=> 14x - 68 = 22=> 14x = 22 + 68=> 14x = 90=> x = 90/14=> x = 45/7Hence, the value of x is 45/7.

Please help me ASAP! Show all your work please.
If we want the area to be more than 225 sqft, and the width is already established as 25, then we can divide 225 by 25 to see what the minimum would be. 225/25 is 9, so this is the minimum. We want a set of possible lengths though, and as long as the pen is over 225 sqft, it's allowed. Therefore, the answer is [tex]x\geq 9[/tex].
hope this helps! comment if it's confusing

help me with which triangle it is and how do I find x?
Answer:
isosceles
x=14
Step-by-step explanation:
isosceles because of the two I symbols on the triangle
x+5=2x-9
5+9=2x-x
14=x
Step-by-step explanation:
it's an isosceles triangle,
as an Isosceles triangle have two equal sides so
→ 2x - 9 = x + 5
→ 2x - x = 5 + 9
→ x = 14
therefore, value of x is 14.
2(14) - 9 = 28 - 9 = 19
14 + 5 = 19

Which linear inequality is represented by the graph?
y < 3x + 2
y > 3x + 2
y < 1/3x + 2
y > 1/3x + 2
Answer:
y > 3x + 2
Step-by-step explanation:
Find gradient using given points:
m = gradient
Formula:
m = Δy/Δx
m = 9/3 = 3
So, equation of line will be:
y = 3x + a
a is 2 as the point (0, 2) is on the line, 2 units above origin point
The options remaining are:
y > 3x + 2 and y < 3x + 2
Consider any point in the shaded region and compare the y-value of that point with the y-value at the same value of x along the line, e.g. (0, 3) is within the shaded region, the y-value of the line at x = 0 is 2, i.e. the coordinates are (0, 2)
3 > 2 ∴ the correct inequality is y > 3x + 2
A points lies on AB¯¯¯¯¯ and is located 2/5 the distance from A to B.
What are the coordinates of the point?

Answer: (8,1)
Step-by-step explanation:
Line AB has a length of (14-4) = 10 units. 2/5 of that length is (2/5)*(10) = 4. The new point would be (8,1).

V of the tray in terms of x.
HELP
Answer:
V(x) = 4x³ - 50x² + 150Step-by-step explanation:
Initial area is 10 in x 15 in.
After cutting the corners and folding, the remaining dimensions are:
Length, l = 15 - 2xWidth, w = 10 - 2xHeight, h = xThe volume of the tray is:
V = lwhV(x) = (15 - 2x)(10 - 2x)x = 4x³ - 50x² + 150(-3,y) and ( 1,-7); m =-4
Answer:
y = 9
Step-by-step explanation:
I dont get the question.
if you are trying to find y, (-7-y)/(1-(-3)) = -4
(-7-y)/4 = -4
-7-y = -16
-y = -9
y = 9
