Since the symbol tells us the angle is 90 degrees we know the 4x and 5x add up to make 90 degrees.
Lets use this to make and form an equation
5x + 4x = 90
9x =90 (collect the x values)
x = 10 (divide both sides 9 to find what x is)
Answer: a.200 + 24x= 500
b. 12.5 sales but since you can’t make half a sale the answer will be 13
1) a
2) c
#1 explanation:
x^4-20x^2=-64
x^4-20x^2+64=0
(find a number that multiplies to the last number aka 64 and adds up to b aka 20)
((x-4)(x-16))^2
x= -2,2,-4,4
same for #2 w different variable and numbers
Then he slept 9 times. Because every hour is 60 minutes, since 1/3 of an hour is 20 mins, it should be 3 times per hour. So using basic math, 3 times 3 equals 9
