i really need help please
Answer:
a = 4, x = 1
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , then
WX = YZ , that is
a² + 5a = 5a + 16 ( subtract 5a from both sides )
a² = 16 ( take the square root of both sides )
a = ± [tex]\sqrt{16}[/tex] = ± 4
Since a > 0 , then a = 4
Also
XY = WZ , that is
x² + 6x = 4x + 3 ( subtract 4x + 3 from both sides )
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
Since x > 0 , then x = 1

Mr. pope lost 10 pounds in one month. At the end of the month, he weighed 240 pounds. By what percentage did Mr. Pope decrease he weight?
a. (4%)
b. (7%)
c.(10)
d.(15%)
Mr. Pope decreased his weight by 4 percent.
What is percentage?A percentage is a portion of a whole thing written as a number between 0 and 100 instead of fraction.
Given that, Mr. pope lost 10 pounds in one month. At the end of the month, he weighed 240 pounds.
we need to find the percentage of decrease of his weight,
So, basically we will use here the concept of percentage change,
Formula = final amount - initial amount / initial amount x 100
Since, he lost 10 pounds and has 240 pounds so, initially he weighted = 240 + 10 = 250 pounds
So, percentage decreased = -10 / 250 x 100 = -4% [minus is the sign for decrease]
Hence, Mr. Pope decreased his weight by 4 percent.

Rhea draws rows and columns on a big piece of paper to make 16 same-sized squares. How many rows and columns does she draw? I
Answer:
4 rows and 4 columns
Step-by-step explanation:
Given
16 same sized squares
Required
Determine the number of rows and columns
Since the shape formed is a square, then the following relationships exist:
[tex]Row * Column = 16[/tex]
[tex]Row = Column[/tex]
[tex]Row * Column = 16[/tex] can then be rewritten as:
[tex]Row * Row = 16[/tex]
[tex]Row^2 = 16[/tex]
Take square roots of both sides
[tex]Row = \sqrt{16[/tex]
[tex]Row = 4[/tex]
[tex]Row = Column[/tex] implies that:
[tex]Row = Column = 4[/tex]

Consider the system of equations 3x + y = 10 and 6x – y = 17 . What is the value of the x-coordinate of its solution?
Answer:
x = 3
Step-by-step explanation:
These are simultaneous linear equations hence, we add them because +y and -y will cancel eachother.
3x + y = 10
6x - y = 17
____________
9x = 27
x = 27/9
x = 3
So, x- coordinate is 3
Answer: the answer should be x = 3

The angles of a triangle add up to 180 degrees.
(3x+5)+(2x+17)+(2x+18)=180
add the ones alike
3x + 2x + 2x=7x
5+17+18=40
so, 7x+40=180
we need to get the variable by itself so we take away 40 first by subtracting it from both sides of the equal sign
7x=140
we take away 7 from x by dividing it- opposite of multiplication is division
x=20
Answer:
x = 20
Step-by-step explanation:
3x+5° + 2x+18° + 2x+17° = 180° (sum of interior angles in a triangle is 180°)
collect like terms
3x + 2x + 2x + 5° + 18° + 17° = 180°
7x + 40° = 180°
solving for x
x = (180 - 40)/7
x = 140/7
x = 20
