What is the area of this figure?

kap26 [50]

Palelogram area:
Knowing the base and the height, the area of the parallelogram is calculated by its formula:
A1 = b * h
Where
b: base
h: height.
We have then
b = root ((- 4 - (- 10)) ^ 2+ (2-2) ^ 2) = 6
h = root ((- 7 - (- 7)) ^ 2+ (3-2) ^ 2) = 1
A1 = (6) * (1) = 6 units ^ 2
Rectangle area
A2 = L * W
Where
L: long
W: Wide
We have then:
L = root ((1 - (- 2)) ^ 2 + (- 3 - (- 4)) ^ 2) = 3.16227766
W = root ((- 4 - (- 2)) ^ 2+ (2 - (- 4)) ^ 2) = 6.32455532
A2 = (3.16227766) * (6.32455532)
A2 = 20 units ^ 2
The total area is the sum of both ares:
A = A1 + A2
A = 6 + 20
A = 26 units ^ 2
Answer:
the area of this figure
A = 26 units ^ 2

X+Y=100<br> 4.5X+20Y=822<br> Elimination, graphing,and substitution methods.

serious [3.7K]

Answer:

y=10

4 SX +20 Y= 822

Elimination

X - 10 -4

UX - 822-20Y

6.5

10 -4 = 822-201

- 4.5 = 822 - 204

15.54=774

4 = 90:13

= -40.129

Cheese sticks that were priced at "10 for 1 dollar are now "4 for 1 Dollar. Find each percent change. Find the percent increase

lina2011 [118]

Cheese sticks were 10. for dollar or 10 cents a piece (10/100 =.10 or 10 cents. now 4 for dollar or ,25 x 100 = 25 cents each (4/100). percent change

.25 - , 10 =.15
,15/,25 = .60
.60 x 100 = 60%

Identify the inequalities A, B, and C for which the given ordered pair is a solution: (0,0)<br>

professor190 [17]

Answer:

Options (A) and (C)

Step-by-step explanation:

A). The given inequality is,

x + y ≤ 2

Solution area of the inequality is the shaded area below the line.

Since (0, 0) lies in the shaded region, ordered pair will be a solution of this inequality.

B). For the inequality y ≤ $\frac{3}{2}x-1$

Since, (0, 0) doesn't lie in the shaded region of this inequality, ordered pair will not be a solution of the inequality.

C). y > $-\frac{1}{3}x-2$

In this graph (0, 0) lies in the shaded region of the inequality therefore, it will be a solution of the given inequality.

Therefore, Options (A) and (C) are the correct options.

Find the real or imaginary solutions of each equation by factoring

anyanavicka [17]

Sum of 2 perfect cubes
a³+b³=(a+b)(x²-xy+y²)
so

x³+4³=(x+4)(x²-4x+16)
set each to zero
x+4=0
x=-4

the other one can't be solveed using conventional means
use quadratic formula
for
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$
for x²-4x+16=0
x= $\frac{-(-4)+/- \sqrt{(-4)^2-4(1)(16)} }{2(1)}$
x= $\frac{4+/- \sqrt{16-64} }{2}$
x= $\frac{4+/- \sqrt{-48} }{2}$
x= $\frac{4+/- (\sqrt{-1})(\sqrt{48}) }{2}$
x= $\frac{4+/- (i)(4\sqrt{3}) }{2}$
x= $2+/- 2i\sqrt{3}$

the roots are
x=-4 and 2+2i√3 and 2-2i√3
