Answer:
W1=0.875.
W2= -1.14
Step-by-step explanation:
(8w-7)(7w+8)
8w(7w+8)-7(7w+8)
56w^2+64w-49w-56
56w^2+15w-56
Solve it by quadratic equation
a=-b+-√(b^2-4ac)/2a
Substitute the values
And you will get 2 answers
a=-56
b=15
c=56

A Sand dune stands 5 feet above sea level. the hill is eroding at a rate of 1 foot per 20 years. let y represent the height of the sand dune after x years. which equation represents the situation
Answer:
5 - (1 + 20) = yx
Step-by-step explanation:
So if 5ft is the original height, we would need to distribute that to decrease in the following years. That is where the 5 - comes from. Next we know that is it is eroding 1 foot in 20 years so that is 5- (1+20) You HAVE to distribute that and not add. Then it equals y the height of the dune in x, the years. Honestly 5 feet above sea level is kinda puny for a sand dune ;P.

find the missing value of X.
9514 1404 393
Answer:
x = 72
Step-by-step explanation:
The sum of interior angles of a pentagon is (5-2)(180°) = 3·180°. The sum of the two right angles is 180°, so we can write the equation ...
180° +2x° +x° +2x° = 3·180°
5x = 2·180 = 360 . . . . divide by °, subtract 180
x = 360/5 = 72 . . . . . . divide by 5
The value of x is 72.

What is the property that allows you to solve a polynomial by setting each 5p factor equal to zero? *
Example:
x^2 + 5x + 6 = 0
(x+3)(x+2) = 0 .... factor
x+3 = 0 or x+2 = 0 ... zero product property used here
x = -3 or x = -2 .... solve each equation for x
------
In general, the zero product property is that if A*B = 0, then either A = 0 or B = 0.

Consider the following Expression.
-3(y+3)=2y+3
What Is the value of y?
Answer:
y= -12/5
Decimal form: -2.4
Step-by-step explanation:
Distribute the negative 3 on the left side
-3y-9=2y+3
Add 3y to both sides
-9=5y+3
Subtract 3 from both sides
-12=5y
Divide by 5 on both sides
y=-12/5 or -2.4

In HIJ below, what is the value of y?
PLEASE ANSWER
Answer:
110
Step-by-step explanation:
The value of x in the given figure is y = 110. Hence option 3 is true.
Given that,
A triangle is shown in the image.
Apply the concept of the triangle that states,
The sum of two opposite interior angles in a triangle is equal to the measure of the exterior angle.
Hence we get;
y° + 20° = 130°
Subtract both sides by 20,
y = 130° - 20°°
y = 110°
Therefore, option 3 is true.
