Minus 16x both sides and add 28 to both sides
x^2-16x+28=0
factor
hmm, what 2 numbers multiply to 28 and add to -16
hmm
1 and 28? nope
2 and 14? yep
since middle term is negative and last tem is positive, both of the factors are negative
(x-14)(x-2)=0
set each to zero
x-14=0
x=14
x-2=0
x=2
x=2 and 14
Answer:
24 feet
Step-by-step explanation:
According to the question, Patricia needs 10 yards of fabric to make curtains for her bedroom she also needs 3 yards of fabric to make a cover for her storage bench
So, she needs 13 yards
converting into feet
1 yard = 3 feet
13 yards x 3 = 39 feet
Now, she already has 15 feet of fabric.
Finding out the difference : 39 - 15= 24 feet
Therefore, she needs 24 feet more of fabric
Answer:
y=2x-5
explanation
m is gradient so rise over run and b is the y intercept which is -5
Answer:
0
Step-by-step explanation:
Solution for cosx=-3/2 equation:
cos((3*pi)/5)*cos((3*pi)/20) = 0
(60*x^3)/(60*x^5) = 0
cos((3*pi)/5)*cos((3*pi)/20) = 0
cos((3*x)/5)*cos((3*x)/20) = 0
1.5/100 = 0
