Answer:
he added the dimensions of the rectangle. He used the wrong formula. the formula he used was length + breadth. He should have multiplied by 2
6x + 8y +8
Step-by-step explanation:
Perimeter of a rectangle = 2 x (L + B)
L = length
b = breadth
2 (3x + 4y + 4. ) = 6x + 8y +8
2 to the second power is 2 x 2 (4) , and 2 to the 3rd power is 2 x 2 x 2 (8)
Answer:
C. 2.
Step-by-step explanation:
The graph descends from the left so the coefficient of the leading term is negative. It is also a cubic equation with zeros of -20, about 6.5 and about 13. so we can write the equation as below. The last 2 values can only be guessed because the x axis only shows values which are multiples of 5.
f(x) = a(x + 20)(x - 6.5)(x - 13) where a is a negative constant.
(This is only an approximation).
By the Remainder theorem, when the expression is divided by (x + 10):
f(-10) = -20 so we have
-20 = a (-10 + 20)(-10-6.5)(-10 - 13)
(10)(-16.5)(-23)a = -20
a = -20 / (10)(-16.5)(-23)
a = -0.0053
When the equation is divided by (x - 10) then f(10) is the remainder so substituting we have as the remainder:
-0.0053(10+20)(10-6.5)(10 -13)
-0.0053 * 30 * 3.5 * -3
= 1.7 approximately.
Looks like the answer is 2.
Answer:
either 7 or 8 but, 8 is most likely.
start with the numbers in the set 2,3,4,5,6,7,8
its supposed to be between 2 and 8
the only number that would work is 7 and 8 if you use 7 you get 2 and if you use 8 you get 3
Angle Q and angle U because they’re the only corresponding pair of the options
