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.

Which expression is equilvalent to (5g-2h)-(3h+8-4g).
Answer:
9g -5h - 8
Step-by-step explanation:
We first have to get everything out of the parentheses, so we take the negative that is surrounding the parentheses and apply it to the equation inside of it, giving us this: 5g - 2h - 3h - 8 + 4g
Then, all we need to do is simplify it into this expression: 9g -5h - 8
Answer:
9g-5h-8
Step-by-step explanation:
(5g-2h)-(3h+8-4g)
Opening the brackets
5g-2h-3h-8+4g
9g-5h-8
A friend gives you six baseball cards for your birthday. Afterward,
you begin collecting them. You buy 4 baseball cards each week. Write
the equation of the line in slope-intercept form and interpret (explain)
the slope and the y-intercept of the line that represents this situation.
Answer:
y=4x+6
Step-by-step explanation:
You originally have 6 cards, and 4 a week will give you the equation 4x. Put it together to get 4x+6, add y to make it the correct equation. hope this helps
Sally bought a sweater for $24.99 with a 25% discount. What is the price of the
sweater after the discount?
There are two ways to do this, the one that makes more logical sense and the faster one
You can first calculate how much is 25%. You do this by $24.99 × 25 ÷ 100
Since you know how much is "discounted", just minus the answer you get above with the original price ($24.99 - $6.2475)
The quicker way is to recognise that "original price" is always 100%. In other words, you can just do 100% - 25% and get 75%. Then, $24.99×75÷100 is your answer.

please help with matrices
Answer:
(1/2) {ad - cb} both expressions
Step-by-step explanation:
Notice that the area of the triangle in question can be calculated as the area of the larger right angle triangle OSQ MINUS the area of the smaller right angle triangle OPR, and MINUS the area of the trapezoid RSQP.
Given the coordinates of the given points, the formulas for area of triangles and of trapezoid, we have the following area subtractions:
1/2 (a + c) (b +d) - 1/2 a* b - 1/2 c (b + b + d)=
= (1/2) { ab + ad + cb + cd - ab - 2 cb -cd } =
= (1/2) {ad - cb}
On the other hand the matrix expression is giving you 1/2 of the determinant of the given matrix such determinant is: ad - cb
Then we see that the equality is correct since (1/2) of the determinant is also :
(1/2) {ad - cb}

The variable q represents a positive integer. Does 3(59 + 9) + 5q represent a number that is greater than, less than, or equal to 4(59 + 6)? Show your work.
Thank you if you awnser this!
Answer:
Depends on the value of q.
Step-by-step explanation:
3(59+9) + 5q = 3(68) + 5q = 204 + 5q
4(59+6) = 260
The value of the inequality equation is 3(59 + 9) + 5q < 4(59 + 6) , when the value of q < 11.2
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the first number be p = 3(59 + 9) + 5q
Now , the value of a = 204 + 5q
And , let the second number be q = 4(59 + 6)
Now , the value of b = 260
Now , for the value of p and q to be equal ,
Substituting the values in the equation , we get
204 + 5q = 260
Subtracting 204 on both sides of the equation , we get
5q = 56
Divide by 5 on both sides of the equation , we get
q = 11.2
Now , when q < 11.2 , the value of a < b
Hence , the inequality equation is 3(59 + 9) + 5q < 4(59 + 6) , when q < 11.2

If the value of "y" varies directly with "X"
and y = -51 when x = 3, find "y" if x = 2.
Enter the number
Answer:
x : 3 :: y : -1
9 : 3 :: y : -1
3y = -9
y = -3
Answer:
-34
Explanation:
Y varies directly as x then the equation relating them is
y= kx ⬅️k is the constant of variation
To find k use the condition y= -51 when x=3
k= -17
y= -17x⬅️equation of variation
when x=2, then
y= -17*2=-34
