Answer:
The pair of binomials are;

and

Step-by-step explanation:
The given expression is

.
If the given quadratic trinomial can be factored as two binomials, then,
By comparing to

, we have

We find

We also know that;

This implies that;

or

When t=11;

When we factor this we obtain;

When t=-11;

When we factor this we obtain;
Square both given expressions and add them together. Make use of trig identities.
(sin(a) +sin(b))^2 = sin(a)^2 +2sin(a)sin(b) +sin(b)^2 = 5/3
(cos(a) +cos(b))^2 = cos(a)^2 +2cos(a)cos(b) +cos(b)^2 = 1
Adding, we have
sin(a)^2 +cos(a^2) +2(cos(a)cos(b) +sin(a)sin(b)) +sin(b)^2 +cos(b)^2 = 2 2/3
Of course, the first and last pairs of terms are 1 and 1, and the middle product is 2cos(a-b), so you have
1 + 2cos(a-b) +1 = 2 2/3
cos(a-b) = 1/3
For every 7 boys there are 5 girls.
Divide the number of boys by the ratio for boys: 28 / 7 = 4
Now multiply that by the ratio for girls:
4 x 5 = 20
There are 20 girls.
279:92=3
600:3=200
the gorila is 200 cm long that is 2 m
162:168=1.5
90:1.5=60 inches
that is how long is the emu
(1 inch= 2.54 cm
2.54*60=152.4 cm thats in cm)
