Answer:
-2
Step-by-step explanation:
brackets first
12 - 9 = 3
Then square it
3^2 = 9
Now multiply by 2
9*2 = 18
finally get - 5 * 4 = - 20
and put them both together
18 - 20 = - 2
Solve the inequality.

Which of the following equations could be solved to determine the length of QR?
O A) QR2 = 202 + 272 - cos 99°
B) QR2 = 202 + 272 - 2(20)(27)
C) cos 99 cos R
QR
20
D) QR2 = 202 + 272 - 2(20)(27) · cos 99°
Answer: D) QR^2 = 20^2 + 27^2 – 2(20)(27) ⋅ cos 99°
Step-by-step explanation:
since you have the lengths of two sides and their included angle, you can use the law of cosines to solve for the missing side. let a, b, and c be the side lengths, and A be side a's respective opposite angle:
the law of cosines states that
a^2 = b^2 + c^2 - 2bc ∙ cosA

Answer:
168000
Step-by-step explanation:
5/14 to the son.
that leaves 9/14 of the total.
these 9/14 we need to split into 1/3rds, as 2/3 of these 9/14 go to the daughter, and then the remaining 1/3 of these 9/14 to the wife.
how do we do that ?
well, here it is simple, as we see right away that the numerator 9 can be easily split into 1/3rds (9/3 = 3).
but in general by multiplying. so 2/3 of 8/14 is
9/14 × 2/3 = 9×2 / 14×3 = 3×2 / 14 = 6/14
and then little surprising 1/3 is
9/14 × 1/3 = 9 / 14×3 = 3/14
now, we know, these 3/14 are 36000.
what we need to know is how much is 14/14 or 1/1 : the whole amount.
well, the easiest way in my opinion is now to bring it to 1/14 (by dividing by the numerator 3) and then multiply it by 14 (the denominator) to bring the sum to the whole (14/14).
it in total, multiply it with the reverse fraction : 14/3
36000 × 14/3 = 12000×14 = 168000

Answer:
x = 1/2 , x = 1/4 , x = 1/3
Step-by-step explanation:
Factor the following equation --> 24x^3 — 26x^2 + 9x — 1 = 0
You will get ----> (2x - 1) (4x - 1) (3x - 1) = 0
Now make all the above expressions = 0 and solve.
2x - 1 = 0 4x - 1 = 0 3x - 1 = 0
+1 +1 +1 +1 +1 +1

find the slope of the line that is perpendicular to the line graphed in the figure
Answer:
- [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m = [tex]\frac{1-(-4)}{1-0}[/tex] = [tex]\frac{1+4}{1}[/tex] = 5
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{5}[/tex]

Find x.
9514 1404 393
Answer:
x = 10AB = 3BC = 11Step-by-step explanation:
If B lies between A and C on a line segment, then ...
AB +BC = AC
(2x -17) +(x +1) = 14
3x = 30 . . . . . . . . . . . . . add 16, collect terms
x = 10 . . . . . . . . . . . divide by 3
AB = 2(10)-17 = 3
BC = 10+1 = 11

Two-thirds a numberx plus 4 is 8.
Answer:
n = 6
Step-by-step explanation:
To solve this you can use an equation such as:
[tex]\frac{2}{3} n+4=8\\\\[/tex]
We need to so for n. Subtract 4 from both sides to get the variable (n) alone. 4 - 4 and 8 - 4 equals:
[tex]\frac{2}{3}n=4[/tex]
So now we divide both sides by 2/3.
This now equals:
[tex]n=6[/tex]
Adjacent sides of Figure 1 are perpendicular. Four sides of Figure 1 are removed to form Figure 2. What is the total length, in units, of the segments in Figure 2?
Answer:
19
Step-by-step explanation:
Here ( left and right) side 8 and 6 are same in both
in fig 1 base side is 1 +2 + 1 =4
so in figure 2 it will be also 4
and at last only 1 unit in fig 1 ( upside) is taken in figure 2
so total addition is...
8 + 6 + 4 + 1
= 19

Answer:
The integers are
1st: n
2nd: n + 1
3rd: n + 2
The words in the problem statement translate into

Solve for n.
2n + 2 = 3n + 12
n = -10
n + 1 = -9
