Find the missing coefficient. (5d − 7)(5d − 6) = 25d2 ++ 42 5 65 –5 –65

Answers

Answer:

-65d

Step-by-step explanation:

(5d − 7)(5d − 6)

$(5d - 7)(5d - 6)$

Multiply it using FOIL method to find the missing term

Multiply 5d inside the second parenthesis and then multiply -7 inside second parenthesis

$5d \cdot 5d= 25d^2$

$5d \cdot -6= -30d^2$

$-7 \cdot 5d=-35d$

$-7 \cdot -6=42$

Now write all the terms together

$25d^2-30d-35d+42$

Combine like terms

$25d^2-65d+42$

HEre -65d is missing

i do believe it is -65d because the equation will look like this in the end
-65d=-65d.

The multiplicative inverse of – 1 in the set {-1,1}is

Answers

Answer: The multiplicative inverse of – 1 in the set {-1,1} is -1.

Step-by-step explanation:

In algebra, the multiplicative inverse of a number(x) is a number (say y) such that

$x* y=1$ [product of a number and its inverse =1]

if x= -1, then

$-1* y=1\Rightarrow\ y=-1$

That means , the multiplicative inverse of -1 is -1 itself.

Hence, the multiplicative inverse of – 1 in the set {-1,1} is -1.

Answers

Answer:

90 degree

Step-by-step explanation:

Three points A, B, and C are added and shown in attached picture.

As the property of inscribed angle in circle:

angle BAC = (1/2) x 88 = 44 deg

As the property of complement angle:

angle ABC = 180 - 89 = 91 deg

As the property of sum of three angles in a triangle:

angle ACB + angle ABC + angle BAC = 180 deg

=> angle ACB = 180 - angle ABC - angle BAC = 180 - 44 - 91 = 45 deg

One more time, we use the property of inscribed angle in circle:

x = 2 x angle ACB = 2 x 45 = 90 deg

Hope this helps!
