The solutions for the quadratic equation are given as follows:
x = -1, x = 7/5
<h3>What is a quadratic function?</h3>
A quadratic function is given according to the following rule:
y = ax^2 + bx + c
The solutions are:
In which:
For this problem, the equation is:
5x² - 2x - 7 = 0.
Hence the coefficients are a = 5, b = -2 and c = -7, and then the solutions are found as follows:
The solutions are:
x = -1, x = 7/5

Answer:
512
Step-by-step explanation:
8 = 2^3
Therefore,
8^3
= (2^3)^3
= 2^(3*3)
= 2^9
= 512
Thus, 8^3 = 512

Answer:
1/5 lawn = 20 min.
? = 1 min
0.05 lawn in 1 minute
rate of 0.05 mowed per minute.
The two angles (6x+4) and 32 degrees are complementary angles. They add to 90 degrees. The two angles are adjacent and form a right angle. The right angle marker is the square marker. Two adjacent right angles form a straight angle (180 degrees)
Add up the angles and set the sum equal to 90. Then solve for x
(6x+4) + (32) = 90
6x+4 + 32 = 90
6x+36 = 90
6x+36-36 = 90-36 .... subtract 36 from both sides
6x = 54
6x/6 = 54/6 ... divide both sides by 6
x = 9
Since x = 9, this means that
6x+4 = 6*9+4 = 54+4 = 58
So the missing angle is 58 degrees (note how 58+32 = 90)
