Answer:
O y = (x + 5) (x + 3)
Step-by-step explanation:
y = (x + 4)² - 1
y = x² + 8x + 15
y = x² + 3x + 5x + 15
y = x(x + 3) + 5(x + 3)
y = (x + 5) (x + 3)
Answer:
440
Step-by-step explanation:
You can write the problem statement in math terms as ...
88 = 0.20 × (what number)
To solve this, divide by the coefficient of the variable, 0.20.
88/0.20 = (what number)
440 = (what number)
The number you're looking for is 440.
_____
Of course you know that 20% = 20/100 = 0.20.
(% is a shorthand way to write /100.)
(2.75 + 4.25) / 50 = 7/50 = 0.14 = 14% <==
Answer:
4
Step-by-step explanation:
x² = 8x - 16
x² - 8x + 16 = 0
(x - 4)² = 0
x = 4
Answer:
Step-by-step explanation:
tn = a + (n-1)*d
t28 = 4 + (27)*-2 27 because 27 = 28 - 1
t28 = 4 + - 54
t28 = 4 - 54
t28 = - 50
