Answer:
Step-by-step explanation:
hello :
h(x) = x² – 5x + 7
h(-2) = (-2)² – 5(-2) + 7 =4+10+7 =21
h(-5) = (-5)² – 5(-5) + 7= 25+25+7 =57
h(-8) = (-8)² – 5(-8) + 7 = 64+40+7=111
Hello!
The total measure of the angles in a triangle always add up to 180 degrees.
The measures that you are given are 37 and 82 degrees. To find what angle x equals, we must first add together the angles that we know:
37 + 82 = 119
To find angle x, we simply subtract 119 from the total number of degrees (180):
180-119 = 61
The measure of angle x is 61 degrees.
I hope this helps you! Have a fantastic day!
Answer:
10
Step-by-step explanation:
Length of boards are the same :
Let number of boards = x
Fraction cut from each board = 3/5
Total fraction cut = 3/5 * x
Fraction left = 1 - 3/5 = 2/5
Total fraction left = 2/5 * x
Total pieces left = 2/5 * x = 4 times length of original board
Note ; original fraction = 1
Hence,
2/5 * x = 4 * 1
2x / 5 = 4
2x = 4 * 5
2x = 20
x = 20 / 2
x = 10
Number of boards = 10
