Answer:

A = 735 cm²

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

Here b = 35 and h = 21 , then

A = 35 × 21 = 735 cm²

Answer: 735 $cm^{2}$

Step-by-step explanation:

To find the are of a parallelogram, you have to multiply the base with the height

As in this case the height is 21 cm and the base is 35 cm

So we multiply 21 cm (the height) and 35 cm (the base)

So, 21 x 35 = 735

So the area of a parallelogram is base x height

(Note that the base can be any side of a parallelogram)

x = -15

Step-by-step explanation:

$x = \frac{2}{3} x - 5$

Collect like terms and simplify

$x - \frac{2}{3} x = - 5 \\ \frac{1}{3} x = - 5$

Cross multiply

$x = - 5 \times 3 \\ \\ x = - 15$

What is the equation in point-slope form of a line that passes through the points (5, −3)(5, −3) and (−2, 9)(−2, 9) ?

Alina [70]

Point sloe is
y-y1=m(x-x1)
slope=m
a ponint is (x1,y1)

slope=(y2-y1)/(x2-x1)
(x,y)
(5,-3)
(-2,9)
slope=(9-(-3))/(-2-5)=12/-7=-12/7
m=-12/7

a point is (5,-3)
x1=5
y=-3
y-(-3)=-12/7(x-5)
y+3=-12/7(x-5)

What is -11 + 3(b + 5) = 7

IRISSAK [1]

Answer:

b=1

Step-by-step explanation:

$\sf -11 + 3(b + 5) = 7$

First, let's regroup, terms,

$\sf 3(b+5)-11=7$

Add 11 to both sides,

$\sf 3(b+5)=7+11$

Simplify, 7+11 = 18,

$\sf 3(b+5)=18$

Now, divide both sides by 3,

$\sf b+5=\frac{18}{3}$

Simplify, 18/3 = 6,

$\sf b+5=6$

Subtract 5 from both sides,

$\sf b=6-5$

$\sf b=1$

Hope it helps! :)

Solve the system of equations. (3x + 4y = 5) (2x - 3y = -8)

vovikov84 [41]

Answer:

the solution is (-1, 2)

Step-by-step explanation:

Let's solve the system

(3x + 4y = 5)

(2x - 3y = -8)

using the method of elimination by addition and subtraction. Notice that if we multiply all terms of the first equation by 3 and all terms of the second by 4, y as a variable will temporarily disappear:

9x + 12y = 15

8x - 12y = -32

-----------------------

17x = - 17, so x = -1.

Replacing x in the second equation by -1, we get:

2(-1) - 3y = -8, or

2 + 3y = 8,

or 3y = 6. Thus, y = 2, and the solution is (-1, 2).
