Need help. Please and thank u
Marina CMI [18]

Answer:

1)

(x + 3)(x + 4) = x^2 + 4x + 3x + 12 = x^2 + 7x + 12

Instead of multiplying 3 and 4 the student added them which gave them the answer of 7 when the correct answer is 12.

2)

a) x^2 + x - 2

b) x^2 - 7x + 10

c) 4x^2 - 1

d) x^2 + 10x + 25

Step-by-step explanation:

a. (x - 1)(x + 2)

x(x) - 1(x) + 2(x) - 1(2)

x^2 - 1x + 2x - 2

x^2 + x - 2

------------------------------------------

b. (x - 5)(x - 2)

x(x) - 5(x) - 2(x) - 5(-2)

x^2 - 5x - 2x + 10

x^2 - 7x + 10

------------------------------------------

c. (2x + 1)(2x - 1)

2x(2x) + 1(2x) - 1(2x) + 1(-1)

4x^2 + 2x - 2x - 1

4x^2 - 1

------------------------------------------

d. (x + 5)^2

(x + 5)(x + 5)

x(x) + 5(x) + 5(x) + 5(5)

x^2 + 5x + 5x + 25

x^2 + 10x + 25

Solve for x. <br> A) 11<br> B) 9<br> C) 6<br> D) 7
DIA [1.3K]

Answer:

Step-by-step explanation:

Angle  BCA is inscribed in that circle.  The rule is that the inscribed angle is half the measure of the arc it intercepts.  The arc it intercepts is arc AB which measures 96 degrees.  That means that

4x+4=\frac{1}{2}(96) and

4x + 4 = 48 and

4x = 44 so

x = 11

Choice A is the one you want.
