Which of the following is a factor of x3 + 2x2 - 25x – 50?
Answer:
(x - 5)(x + 2)(x + 5)
Step-by-step explanation:
x³ + 2x² - 25x - 50
x³ + 7x² - 5x² - 35x + 10x - 50
x(x² + 7x + 10) - 5(x² + 7x + 10)
(x - 5)(x² + 7x + 10)
(x - 5)(x² + 2x + 5x + 10)
(x - 5)(x(x + 2) + 5(x + 2))

-3x + 7 = 5x + 4 - 8x
looking for help to answer with work ?
Answer:
no solutions
Step-by-step explanation:
-3x + 7 = 5x + 4 - 8x
Combine like terms
-3x+7 = -3x+4
Add 3x to each side
-3x+7+3x = -3x+4+3x
7 = 4
This is not a true statement so there are no solutions
Which answer matches this description? 15 minus the quotient of 50 and 10 15 = (50 - 10) (50 - 15) + 10 (50 - 10) - 15 15 - (50 = 10)
Answer:
The bottom left one
15 - (50 / 10)
Step-by-step explanation:
15 minus the quotient of 50 and 10
Keywords:
Minus: subtraction meaning we would use (-)
Quotient: Quotient is the outcome of division (/)
15 minus the quotient of 50 and 10
Replace minus with (-)
15 - the quotient of 50 and 10
Get rid of quotient and add a division sign between 50 and 10
15 - 50 / 10
Add parenthesis
15 - (50 / 10 )
2 intersecting lines are shown. A line with points T, R, W intersects a line with points S, R, V at point R. Angle T R V is 95 degrees. mAngle SRW = °
Answer:
m<SRW = 95degrees
Step-by-step explanation:
If a line with points T, R, W intersects a line with points S, R, V at point R with the point of intersection at R, this means that;
m<TRV = m<SRW (vertically opposite angles)
Since m<TRV = 95 degrees, hence <SRW = 95degrees

Which of the following is a rational number but not an integer?
188, 13 2/5, -4, or -51
Answer:
Option C
Step-by-step explanation:
Rational numbers are numbers of the form p/q, where p and q are integers and q not equal to zero.
Integers are number of the form p/q , where q = 1
Option A : 188 => integer and rational
Option B: 13 => integer and rational
Option C :2/5 => rational but not integer ( because q = 5 and not 1 )
Option D : - 51 => integer and rational
Answer:
13 2/5Step-by-step explanation:
As,
Integers includes whole numbers, and negative of the whole numbers.
And Rationals includes every fraction, Integers and negative fraction.
So,
188, -4, and 51 are both Integers and Rationals.
But,
Only 13 2/5 is a mixed fraction included only in rationals and not in Integers

Step 1: Define
Identify
Point (-6, 2)

Step 2: Find
Substitute in variables [Point-Slope Form]: y - 2 = 1/2(x - -6)Simplify: y - 2 = 1/2(x + 6)A ladder leans against the side of a house. The angle of elevation of the ladder is 68° when the bottom of the ladder is 16 it from the side of the house. Find the
length of the ladder Round your answer to the nearest tenth.
Answer:
The length of the ladder = 6.5077 ft
Step-by-step explanation:
Given A ladder leans against the side of a house
Given the angle of elevation of the ladder is 68° when the bottom of the ladder is 16 ft from the side of the house
Let 'C' be the point of observation.
Given CA= 16 ft
From right angle triangle
x = 16 × cos 68°
x = 16 × 0.4067
x = 6.5077
x = 6.5 ft
The length of the ladder = 6.5 ft
syd is on a cliff 43 feet above sea level ingrid dove into the sea and took photos of fish at 17 feet below sea level how far apart are syd and ingrid?
Answer:
60 ft
Step-by-step explanation:
Position of Syd = +43
Position of Ingrid = - 17
To find the distance between them, add the absolute value
I +43 I + I-17I = 43 + 17 = 60
Answer:
let's take the postion of sea level 0
such that
syds on a cliff 43 ft above sea level
his position = 43 ft
Ingrid is 17 feet below sea level so his position = 17 ft in the opposite direction as that of Syd.
since syd is 43 feet away from sea level, that is 0, and sea level is 17 feet away from Ingrid.
distance between syd and Ingrid = 43 + 17
= 60 ft

whats the angle of J
Answer:
<J = 59
Step-by-step explanation:
Since this is an isosceles triangle, <J and <H are the same
The sum of the angles in a triangle are 180
62+ <J + <H =180
62+ <J + <J = 180
62 + 2 <J =180
Subtract 62 from each side
2 < J = 180-62
2 < J = 118
Divide by 2
<J =118/2
<J = 59
Answer:
∠J = 59 °
Step-by-step explanation:
Its two angle is equal so, it is isosceles triangle.
so, ∠J and ∠H are same.
We know that sum of angles of triangle is 180°.∠J = ∠H .. ( in isosceles triangle two side are equal).
so, ∠J = ∠J
62° + ∠J + ∠ J = 180°
combine like terms
62° + ∠2J = 180°
Subtract 62 from each side
62° - 62° + ∠2J = 180° - 62°
∠2J = 118°
Divide each side by 2
∠2J/2 = 118° / 2
∠J = 59 °
Verification :-
∠J + ∠H + 62° = 180°
59° + 59° + 62° = 180°. .( ∠J =∠H - proved above)
118° + 62° = 180°
180° = 180°

The length of a rectangle 4 yd is longer than its width. If the perimeter of the rectangle is 68 yd, find its length and width.
w + 4
------------------------
l l
l l w
l l
------------------------
Perimeter would be the sum of all the sides so: (w+4) + w + (w+4) + w
Perimeter is 60 yards according to your problem so: (w+4) + w + (w+4) + w = 60 yds
1.Simplify/combine like terms:
w + 4 + w + w + 4 + w =
4w + 8 =
Now it's a 2-step algebra equation
4w + 8 = 60
2.Subtract 8 on both sides
4w = 56
3.Divide both sides by 4
w = 14

Some one say that if you multiply or divide each side of an inequality by a negative number, the inequality sign changes directions. He give an example: -2x < 6, then x > -3. Is the statement true or false?
Answer:
True
Step-by-step explanation:
Answer:
Step-by-step explanation:
It is true!
Let's say we subtract 6 from both sides
-2x -6< 0 Now Let's add 2x to both sides
-2x + 2x - 6 < 0 + 2x
- 6 < 2x We did so we would be dividing by a number greater than 0. Divide by + 2
-6/2 < 2x / 2
-3 < x Notice you still get the open end of the inequality sign closest to the x without changing the direction of the inequality.
