Answer:

Width = (x + 8) inches.

Step-by-step explanation:

The  area of the quilt is the length times the width and if we know the area and the length we can find the width by area / length.

Area = x^2 + 18x + 80 = (x + 10)(x + 8) - now we know that the length is (x + 10) so the width must be (x + 8) inches.

Let me know if you require more explanation.

Two angles are supplementary one angle measure 12 more than the other find the measures
Furkat [3]
We have a + b = 180 and a = 12 + b;
Then, 12 + b + b = 180;
12 + 2b = 180;
2b = 168;
b = 84;
a = 12 + 84;
a = 96;

Answer:

See below for answers

Step-by-step explanation:

Do you mean f(x)=2sin(x-1) or f(x)=2sin(x) -1?

Use the formula f(x)=asin(bx+c)+d where |a| is the amplitude, -\frac{c}{b} is the phase shift, d is the vertical shift, and the period is \frac{2\pi}{|b|}.

Assuming your first case is true, the amplitude would be |a|=|2|=2, your period is \frac{2\pi}{|1|}=2\pi, and your midline/vertical shift is d=0.

Assuming your second case is true, everything but the vertical shift stays the same. It would be d=-1 in this case.

makkiz [27]

Answer:

B) 12p - 10

Step-by-step explanation:

J = 3p

A = 2(3p) = 6p

S = 3p - 10

add together:

3p + 6p + 3p - 10 = 12p - 10
