The diagram shows a trapezium.
x-4
Diagram NOT
accurately drawn
2x
x + 5
All the measurements are in centimetres.
The area of the trapezium is 351 cm2.
(a) Show that 2x2 + x - 351 = 0
Answer:
Step-by-step explanation:
The area of a trapezium is given as;
Area = [tex]\frac{1}{2}[/tex](a + b)h
where: a is the length of the upper side, b is the length of its base and h is its height.
This implies that; a = x - 4, b = x + 5, h = 2x and area = 351
Thus,
351 = [tex]\frac{1}{2}[/tex]((x - 4) + (x + 50)) 2x
= (x - 4 + x + 5) x
531 = (2x + 1) x
= 2[tex]x^{2}[/tex] + x
So that;
2[tex]x^{2}[/tex] + x - 531 = 0
This gives a quadratic equation.

During a scuba dive, Lainey descended to a point 23 feet below the ocean surface. She continued her
descent at a rate of 23 feet per minute. Enter an inequality you could solve to find the number of minutes
she can continue to descend if she does not want to reach a point more than 97 feet below the ocean
surface. Use t to represent the variable for the minutes Lainey can continue to descend.
The inequality is
t (select)
t (23) ≤ 97 - 23
The minus 23 at the back represents the feet she already descended before what the question wants us to calculate
≤ is used instead of < because it states more than, not "equal or more than" (meaning 97 sharp is fine)

15 divided by 112.5=7.5
15 divided by 112.5=75
112.5 divided by 15=7.5
112.5 divided by 15=75
Answer:
112.5 divided by 15=7.5
112.5 divided by 15=7.5 equation is true answer.
Given option are:
15 divided by 112.5 = 7.5
15 ÷ 112.5 = 0.1333
This option is wrong.
15 divided by 112.5 = 75
15 ÷ 112.5 = 0.1333
This option is wrong.
112.5 divided by 15 = 7.5
112.5 ÷ 15 = 7.5.
This option is right.
112.5 divided by 15 = 75.
112.5 ÷ 15 = 7.5.
This option is wrong.
Therefore, the correct equation is 112.5 divided by 15=7.5

Answer:
x<-3
Explanation:
Divide both sides by -2 to isolate x.
Since you have divided by a negative number and it changed the positive number to a negative one, you'll need to change the direction of the sign to now reflect that.

Find the equation of the circle centered at $(1,-4)$ with radius 3.
Write your equation in the form "$(x - h)^2 + (y - k)^2 = r^2$".
Answer:
[tex](x-1)^2+(y+4)^2=9[/tex]
Step-by-step explanation:
The equation of a circle is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where (h, k) is the center and r is the radius.
The center of the circle is (1, -4).
And the radius is 3.
Substitute:
[tex](x-(1))^2+(y-(-4))^2=(3)^2[/tex]
Simplify. Thus, our equation is:
[tex](x-1)^2+(y+4)^2=9[/tex]
Answer: (x-1)^2+(y+4)^2=9
