Step-by-step explanation:

A=62-8=54

if the angles are complementary that means that their sum is 90degrees, so 54+5x+21=90

5x=90-75=15

=>B=15+21=36

6. Use synthetic substitution to evaluate the polynomial P(x) = x - 4x² + 4x – 5 for x = 4

Tatiana [17]

Answer:

When x=4

P(x) =4 - 4(4)^2 + 4(4) -5

=4 - 4(16) + 16 -5

=4 - 64 +11

= -60 + 11

= -49

What is the length of AC?

Alenkasestr [34]

So in order to find line AC you must find line AD and DC then plus them together.

to find AD use Pythagoras theorem
a^2 = c^2 - b^2
AD^2 = 7.5^2 - 6.5^2
AD^2 = 56.25 - 42.25
AD^2 = 14
square root both sides to get rid of the ^2
AD ≈ 3.7 or 3.74

Do the same for DC
DC^2 = 10^2 - 6.5^2
DC^2 = 100 - 42.25
DC^2 = 57.75
DC ≈ 7.6

now plus AD and DC which should give u 11.3

WILL MARK BRAINLIEST <br> in detail, what would you do in order to graph y = 3x -5

Hunter-Best [27]

So first, you need to identify the parts of this equation.

3x is the slope of the line, which is $\frac{3}{1}$ .
