1.Factor: 4x^2+28x-36
2.Factor: 125x^6-27y^15
3.Multiply: (4x-7)(5x-8)
Answer:
1. 4(x² + 7x - 9)2. (5x² - 3y⁵) (25x⁴ + 15x²y⁵ + 9y¹⁰)3. 20x² - 67x + 56Step-by-step explanation:
1. factor 4x^2+28x-36
= 4x² + 28x - 36
re-write 36=4*9, and 28=4*7
= 4x² + 4 * 7x - 4 * 9
factor out common term:
= 4(x² + 7x - 9)2. factor 125x^6-27y^15
= 125x⁶ - 27y¹⁵
=(5x²)³ - (3y⁵)₃
apply difference of cubes: x³-y³ = (x-y)(x²+xy+y²)
= (5x² - 36y⁵)(5²x⁴ + 5 * 3x²y⁵ + 3²y¹⁰)
refine:
= (5x² - 3y⁵) (25x⁴ + 15x²y⁵ + 9y¹⁰)3. multiply (4x-7)(5x-8)
apply the FOIL method
= 4x * 5x + 4x (-8) + (-7) * 5x + (-7) (-8)
= 20x² - 67x + 56ASAP

HELP ME PLZZZ I NEED HELP WITH THIS
Answer:
-5 degrees (the first one )
Step-by-step explanation:
Divide -10 by 2 to get the number of degrees in F were lowered in one hour like so:
-10 / 2
= -5
Therefore, the temperature dropped 5 degrees in one hour.

Answer:
24
Step-by-step explanation:
A negative integer times a negative integer is the same as a positive integer times a positive integer, so this would be the same as (8)(3) which is 24.

General Formulas and Concepts:
A box at an angle signifies a 90° angle.
The 2 angles that add up to 90° are called Complementary AnglesStep-by-step explanation:
Step 1: Set up equation
The 2 angles are Complementary Angles. They must add up to 90°.
(6y + 5) + (8y + 1) = 90
Step 2: Solve for y
Combine like terms: 14y + 6 = 90Subtract 6 on both sides: 14y = 84Divide both sides by 14: y = 6Answer:
y = 6
Step-by-step explanation:
So, the two angles sum up to 90 degrees.
Based on that, form an equation;
6y + 5 + 8y + 1 = 90
simplify,
6y + 5 + 8y + 1 = 90
14y + 6 = 90
inverse operations,
14y + 6 = 90
-6 -6
14y = 84
/14 /14
y = 6

How do i get A and B ?
Answer:
a=60°
b=300°
Step-by-step explanation:
the triangle is equilateral so all angles are 60 °
a = 60°
b=360 - 60 =300°
Answer:
A is 60°, B is 300°
Step-by-step explanation:
If you look closely, you can tell that this circle is divided into 6 triangles, but there is only one showing. This triangle is 1/6 of the circle.
You can find B by find 1/6 of 360° and subtracting that from 360, (a full circle is 360°)
1/6 of 360° is 60°
360° - 60° = 300°, so B is 300°
Now lets find A. Triangles are 180°. This triangle is obviously an equilateral triangle, so the measurements will all be the same.
180 ÷ 3 is 60, so A is 60°
I hope this helped, please mark Brainliest, thank you!

what is the slope of (19,14) & (21,19)
Step-by-step explanation:
Hey there!
Given; The points are; (19,14) and (21,19).
Note: Use slope formula.
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
Put all values.
[tex]m = \frac{19 - 14}{21 - 19} [/tex]
Simplify it.
[tex]m = \frac{5}{2} [/tex]
Therefore, slope(m)= 5/2.
Hope it helps...
Answer:
slope = 5/2
Step-by-step explanation:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
[tex]\frac{19-(14)}{21-(19)}[/tex]
m=[tex]\frac{5}{2}[/tex]

Given m||n, find the value of x.
Answer:
x = 20
Step-by-step
Because the two angles are o the same line ( line t) we know that x+160 will equal 180 degrees, so to solve
180-160= 20
