Remember that complementary angles are the angles whose sum is 90 degrees, so for example if angle
and angle
are complementary; then
.
In our case we have an angle a whose measure is 42° and and angle b, repented by x, whose measure we don't know; similarly:
We can conclude that the equation that represents this situation with x representing the measure of ∠b is <span>
42+x=90.</span>
The answer would be C:9 because you would have to substitute the 1/2 into f(x) so it would be
f(1/2)= 3( (2*1/2) + 1)
= 3(1+1)
= 3^2
= 9
Hope that helped!
Step-by-step explanation:
10 + 10 + 10 = 30
10 + 5 + 5 = 20
5 + 2 + 2 = 9
1 + 5 + 10 = 16
N in the diagram has the value of 8 cm.
The product (4 cm)*(6 cm) is equal to the product (3 cm)*(n).
Answer:Using Them. Example: (y+1)2. We can use the (a+b)2 case where "a" is y, and "b" is 1: Example: (3x−4)2. We can use the (a-b)2 case where "a" is 3x, and "b" is 4: Example: (4y+2)(4y−2) We know the result is the difference of two squares, because: Example: which binomials multiply to get 4x2 − 9.
