Answer:

144

Step-by-step explanation:

First we can start by replacing x with the value (2)

$120 + 18(2) - 3 {(2)}^{2}$

$120 + 36 - 3(4)$

$120 + 36 - 12$

Therefore the final answer is 144

In triangle XYZ, angle Y = 45º and angle Z = 60º. If XZ = 4, then what is XY?

Katena32 [7]

Answer:

$XY = 4.9$

Step-by-step explanation:

Given

$XZ= 4$

$\angle Y = 45$

$\angle Z = 60$

Required

Determine the measure of side XY

To do this, we make use of sine law. This is as follows:

$\frac{a}{\sin\ A} = \frac{b}{\sin\ B} = \frac{c}{\sin\ C}$

In this case:

$\frac{4}{\sin(45)} = \frac{XY}{\sin(60)}$

Cross Multiply

$XY * \sin(45) = 4 * \sin(60)$

$XY * 0.7071 = 4 * 0.8660$

Make XY the subject

$XY = \frac{4 * 0.8660}{0.7071}$

$XY = \frac{3.4640}{0.7071}$

$XY = 4.89888276057$

$XY = 4.9$ -- <em>approximated</em>

Noah drew 22 hearts and 76 circles. What is the ratio of circles to all the shapes?

dimulka [17.4K]

You would make a fraction with circles on the top which would be 76. Then you would add 22 to 76 and get 97 because that is the number of all of the shapes. That would mean your fraction would be 76/97. If u want to simplify that is up to you.

Use the point-slope equation to identify the slope and the coordinates of a point

ioda

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 4 = $\frac{1}{2}$ (x - 1) ← is in point- slope form

with slope m = $\frac{1}{2}$

and (a, b) = (1, 4 ) ← point on the line
