Answer:
a) (5x + 6)(2x + 8)
Step-by-step explanation:
10x² + 52x + 48
(5x + 6)(2x + 8)
Answer:
(-2, 3 )
(-1, 2
)
(0, 2)
(1, 1)
(2, 1)
Step-by-step explanation:
You just simply substitue the values given into the equation, and the answer worked out will be the value of y.
a = - × -2 + 2 = 1 + 2 = 3
b = - × -1 + 2 = + 2 = 2
c = - × 0 + 2 = 0 + 2 = 2
d = - × 1+ 2 = - + 2 = 1
e = - × 2+ 2 = -1 +2 = 1
Hope this helps you :)
Answer:
Step-by-step explanation:
Solve this by writing an equation of ratios:
1 a
----- = -----
√3 5
5
Then 5 = √3*a, or a = -----------
√3
5√3
Rationalize the denominator: a = ----------

Answer:
420
Step-by-step explanation:
The number of students in the school is unknown, so we'll call it x.
55% of the number of students are girls.
There are 321 girls.
55% of x = 231
0.55x = 231
x = 231/0.55
x = 420
Answer: 420
