For this case we must solve the following expression:

$-11 (-7)$

By law of multiplication of signs we have to:

$- * - =+\\- * + = -\\+ * - = -\\+ * + =+$

Also we must find the product of 11 and 7, this is equivalent to:

$11+ 11+ 11+ 11 +11+ 11 + 11 = 77$

Thus, the result of the expression is +77.

Answer:

$-11 (-7) = 77$

Answer: g^2+2g+1

Step-by-step explanation: Since she wants each side to be 1 inch larger, each side has a length of g+1. You need to find the area by squaring (g+1).

Write this as (g+1)(g+1). Use the FOIL method to get g^2+g+g+1. Simplify this to g^2+2g+1.

If the point (x,square root 3/2) is on the unit circle, what. is x?

galina1969 [7]

Answer:

$x=\pm\frac{1}{2}$

Step-by-step explanation:

On a unit circle, $(x,y)=(\cos\theta,\sin\theta)$ , so $\sin\theta=\frac{\sqrt{3}}{2}$ in this case. If you look at the attached circle, the only time that the y-coordinate is $\frac{\sqrt{3}}{2}$ is when $x=-\frac{1}{2}$ and $x=\frac{1}{2}$ , which correspond to angles of $\theta=\frac{2\pi}{3}$ and $\theta=\frac{\pi}{3}$ respectively
