Step-by-step explanation:
Please see the attached picture.
In △BCD
∠BDC= 180° -90° (adj. ∠s on a str. line)
∠BDC= 90°
Applying Pythagoras' Theorem,
(BD)² +(DC)²= (BC)²
(BC)²= 6² +4²
(BC)²= 52 -----(1)
In △ABD
Applying Pythagoras' Theorem,
(AD)² +(BD)²= (AB)²
(AB)²= x² +6²
(AB)²= x² +36 -----(2)
In △ABC
Applying Pythagoras' Theorem,
(AB)² +(BC)²= (AC)²
(AB)² +(BC)²= (x +4)²
Substitute (1) and (2):
x² +36 +52= (x +4)²
x² +88= x² +2(x)(4) +4² (simplify, expand)
x² +88= x² +8x +16
8x +16= 88 (-x² on both sides)
8x= 88 -16
8x= 72
x= 72 ÷8
x= 9
Given a polynomial f(x), if (x − 4) is a factor, what else must be true? f(0) = 4 f(0) = −4 f(4) = 0 f(−4) = 0
Question:
Given a polynomial f(x), if (x − 4) is a factor, what else must be true?
f(0) = 4 f(0) = −4 f(4) = 0 f(−4) = 0_______________________________________
Solution:
f(x) is a polynomial.
(x - 4) is a polynomial of f(x).
By converse of factor theorem: If (x - a) is a factor of f(x), then, f(a) = 0.
On comparing (x - 4) with (x - a), we get,
a = 4So,
f(a) = 0
=> f(4) = 0

thabo rounded the number of marbles to the nearest 5. His answer was 340. write down 2 possible numbers for the actual number of marbles.
Answer:
338 or 335 they both get rounded of to the nearest 5
2 possible numbers for the actual number of marbles 338 and 335, are rounded to the nearest 5.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, Thabo rounded the number of marbles to the nearest 5 and his answer was 340.
Therefore, 2 possible numbers for the actual number of marbles could be
Whether it's 338 or 335, both numbers are rounded to the nearest 5.

What is the average rate of change of f(x) from 3 to 6?
−112
12
−12
112
Answer:
12
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 3, 6 ] , then
f(b) = f(6) = 6² + 3(6) + 2 = 36 + 18 + 2 = 56
f(a) = f(3) = 3² + 3(3) + 2 = 9 + 9 + 2 = 20 , then
average rate of change = [tex]\frac{56-20}{6-3}[/tex] = [tex]\frac{36}{3}[/tex] = 12

Answer:
A
Step-by-step explanation:
Steps to take to determine the answer
Because the length is in yards, it has to be converted to footFind the area of the patio using the length and width measured in footDetermine the area of the square brickMultiply the cost of the brick by the area1 yards = 3 foot
5 x 3 = 15 foot
Area of a rectangle = length x breadth
15 x 10 = 150 ft^2
Cost = 150 x 4 = $600
