Answer:
Step-by-step explanation:
In this question we will solve the polynomials by adding or subtracting the similar terms.
1). (-3x² - 8x + 2) + (-5x² - 9x - 2)
= (-3x²- 5x²) - (8x + 9x) + (2 - 2)
= (-8x²) - 17x + 0
= -8x² - 17x
2). (-2x² + 7x - 1) - (8x² - 6x + 5)
= (-2x² - 8x²) + (7x + 6x) - (1 + 5)
= -10x² + 13x - 6
3). (5x²- 5xy - 10y²) + (5x²+ 5xy + 10y²)
= (5x² + 5x²) + (-5xy + 5xy) + (-10y² + 10y²)
= 10x²
4). (2 + 8x + 4x²) - (9 + 6x + 2x²)
= (2 - 9) + (8x - 6x) + (4x² - 2x²)
= -7 + 2x + 2x²
5). (4x³ + 5x²+ 3x) - (3x³ + 6x²- 1)
= (4x³ - 3x³) + (5x² - 6x²) + 3x + 1
= x³- x² + 3x + 1

18 1/4 as an improper fraction
Answer:
73/4
Step-by-step explanation:
18x4 = 72. 72 + 1 = 73
Answer: 73/4
Step-by-step explanation:
An improper fraction is simply a fraction in which the numerator is larger than the denominator. Thus, simply convert 18 into fourths, 72/4, then add 1/4 to get 73/4

Answer:
120
Step-by-step explanation:
all angles of a triangle add up to 180. 180-15-45= 120.
:D
brainliest pls
Given :
Measure of an angle = 15°
Measure of the second angle = 45°
Let the measure of the third angle be x.
We know that :
▪︎Sum of all angles of a triangle = 180°[angle sum property]
Which means :
[tex] =\tt 15 + 45 + x = 180[/tex]
[tex] =\tt 60 + x = 180[/tex]
[tex] =\tt x = 180 - 60[/tex]
[tex]\hookrightarrow\color{plum}\tt \: x = 120°[/tex]
Thus, the measure of the third angle = 120°
Since the sum of all these angles is equivalent to 180°[15+45+120=180] we can conclude that we have found out the correct measure of the third angle.
Therefore, the correct option is (C) 120

Answer:
11/21/52100-1-1/2-1/5-2-10Value of x? I need this very quickly.ASAP.
Answer:
x = 5
Step-by-step explanation:
The sum of the angles of a triangle is 180°.
(180 - 18x + 5) + (-1 + 8x) + 46 = 180
⇒ 180 - 18x + 5 - 1 + 8x + 46 = 180
⇒ -10x + 230 = 180
⇒ -10x = -50
⇒ x = 5
Becky invests £5000 for 2 years in a bank account.
She gets simple interest at a rate of 3% per year.
Work out the total amount of interest Becky gets by the end of 2 years.
Answer:
£5300
Step-by-step explanation:
-first you find 3% of 5000, which is £150
-£150 only represents the intreset for one year, but becky invests for 2 years, so:
150*2= 300
-add them together:
300+5000=5300

The properties of similar triangles.In Geometry, two (2) triangles are said to be similar when the ratio of their corresponding sides are equal and their corresponding angles are in congruence.
By applying the properties of similar triangles, we have this expression:
AB/DE = BC/CD
Substituting the given parameters into the expression, we have;
9/6 = 15/x.

The value of x is: x = 35.57.
Here, we have,
given that,
from the given diagram, we get,
it is a right angle triangle,
base = x
hypotenuse = 37
and angle = 16°
now, we know that,
cos θ = adjacent / hypotenuse
so, we get,
cos 16° = x/37
The value of cos 16° is equal to the x-coordinate (0.9613).
∴ cos 16° = 0.9613.
=> 0.9613 = x/37
=> x = 35.57
Hence, The value of x is: x = 35.57.

Translate the figure 7 units left and 3 units down.
Plot all of the points of the translated figure.
You may click a plotted point to delete it.
Answer: The coordinates should be... (2,0) (-6,3) (-6,-2)
Step-by-step explanation:
The translation is (-6, -2), (-6, 3) and (0, 2).
What is translation?Translation means the displacement of a figure or a shape from one place to another. In translation, a figure can move upward, downward, right, left or anywhere in the coordinate system. In translation, only the position of the object changes, its size remains the same.
we have to translate 7 units left and 3 units down.
So, 7 units left shifting to the negative x-axis and 3 units down to negative y axis.
So, the coordinates will be (-6, -2), (-6, 3) and (0, 2)

The budget for a school dance is $390.00. Decorations and refreshments cost $150.00. The band charges a fee of $100.00 plus an additional $35.00 per hours. What is the maximum number of hours the school can have the band play at the dance?
Answer:
The maximum number of hours the school can have the band play at the dance is 4.
Step-by-step explanation:
150 + 100 + 35x ≤ 390
250 + 35x ≤ 390
subtract 250 from both sides
35x ≤ 140
divide by 35 on both sides
x ≤ 4
