Answer:

Step-by-step explanation:

To determine a + a² just substitute the value of a.

Given a = 6.

Therefore, a + a² would become 6 + 6² = 6 + 36

= 42

∴ a + a² = 42

G(x) = 3x + 1; Find g(-8)

gregori [183]

Answer:

g(-8) = -23

Step-by-step explanation:

g(x) = 3x + 1 Plug in g(-8)

g(-8) = 3(-8) + 1 Multiply 3 by -8

g(-8) = -24 + 1 Add 1 to -24

g(-8) = -23

Given the triangle below, find the length of XW . Round your answer to the nearest tenth.

Ghella [55]

Check the picture below.

so let's use the law of sines then

$\textit{Law of sines} \\\\ \cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{1.9}{sin(Z)}~~ = ~~\cfrac{XZ}{sin(Y)}\implies \cfrac{1.9}{sin(89^o)}~~ = ~~\cfrac{XZ}{sin(70^o)}\implies \cfrac{1.9\cdot sin(70^o)}{sin(89^o)}=XZ \\\\[-0.35em] ~\dotfill$

$cos(21^o)=\cfrac{\stackrel{adjacent}{XW}}{\underset{hypotenuse}{XZ}}\implies XZ\cdot cos(21^o)=XW \\\\\\ \cfrac{1.9\cdot sin(70^o)\cdot cos(21^o)}{sin(89^o)}=XW\implies 1.7\approx XW$

quick observation, the picture of the triangle is very misleading, since those angles as drawn are not good representers of the angles values.

Write an algebraic

MatroZZZ [7]

Answer:

x = 115 - p

Step-by-step explanation:

generally in algebra you will use the letter "x" to represent a value you do not know, so it wants an algebraic expression for "p subtracted from 115", this can be rewritten as 115 - p. So the unknown value "x" is equal to 115 - p.
