19) No, 3 should multiply both x and 2. As they, (x+2) are both inside the parentheses. The correct answer should be 3x + 6.

20) No, when it comes to exponents and multiply, exponents is done first before multiply. Therefore, Brett should square 3 first before multiplying it by 2. the correct steps should be

2 * 3^2 + 5

= 2* 9 + 5

=18 + 5

frutty [35]

Answer:

S = R θ where θ is in radians

If θ = 2 pi then S = 2 pi R the circumference of the circle

θ = S / R = 9.7 / 9 = 1.08 rad

Since 1 rad = 360 / (2 pi) = 57.3 deg

the angle included = 1.08 rad * 57.3 deg/rad = 61.9 deg

Solve for c.<br> a(c+b) = d.

kipiarov [429]

Answer:

Step-by-step explanation:

Hello,

we assume that a is different from 0 otherwise there is not much we can say on c and then we can write

a(c+b)=d

<=> ac+ab=d

<=> ac = d - ab

<=> $c = \dfrac{d-ab}{a} =\dfrac{d}{a}-b$

Hope this helps
