Answer:

x + 12 = -15 and -27

Step-by-step explanation:

Word math to equation conversion is,

<u>x + 12 = -15</u>

Then solution i. e.

x + 12 = -15

=> x = -15 - 12

=> x = -27

<u>Hence, answer of the solution is -27 (Ans)</u>

Answer:

The width of the original rectangle on the left is $5\ m$

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

Let

z -----> the scale factor

a ----> perimeter of the reduced rectangle on the right

b ----> perimeter of the original rectangle on the left

$z=\frac{a}{b}$

we have

$a=24\ m$

$b=30\ m$

substitute

$z=\frac{24}{30}=0.8$

step 2

Find the width of the reduced rectangle on the right

we know that

The perimeter of rectangle is equal to

$P=2(L+W)$

we have

$L=8\ m$

$P=24\ m$

substitute and solve for W

$24=2(8+W)$

$12=(8+W)$

$W=12-8=4\ m$

step 3

Find the width of the original rectangle on the left

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

Let

z -----> the scale factor

y ----> the width of the reduced rectangle on the right

x ----> the width of the original rectangle on the left

$z=\frac{y}{x}$

we have

$y=4\ m$

$z=0.8$

substitute and solve for x

$0.8=\frac{4}{x}$

$x=\frac{4}{0.8}$

$x=5\ m$

Jessica used Fraction 2 over 3 yard of fabric to make a scarf. Can she make 2 of these scarves with Fraction 1 and 3 over 4 yard

aleksandrvk [35]

Yes,

2/3 + 2/3 = 4/3 = 1 1/3

1 1/3 < 1 3/4

Answer:

TV = 48

Step-by-step explanation:

We can see that SW is twice the length of WV

42/21 = 2

We can find the length of TV this way

TU = 16 x 2
TU = 32
TV = 32 + 16
TV = 48

F (x) = 2 (x + 1)^2 - 1

Ivenika [448]

Answer:

Equation: y = x²

(-2, 4)
(0, 0)
(2, 4)

Equation: f(x) = 2(x + 1)² - 1

(-2, 1)
(0, 1)
(2, 17)

Step-by-step explanation:

Equation: y = x²

when x = -2, y = (-2)² = 4 ⇒ (-2, 4)
when x = 0, y = (0)² = 0 ⇒ (0, 0)
when x = 2, y = (2)² = 4 ⇒ (2, 4)

Equation: f(x) = 2(x + 1)² - 1

f(-2) = 2(-2 + 1)² - 1

= 2(-1)² - 1

=2(1) - 1

= 1

Therefore, (-2, 1)

f(0) = 2(0 + 1)² - 1

= 2(1)² - 1

=2(1) - 1

= 1

Therefore, (0, 1)

f(2) = 2(2 + 1)² - 1

= 2(3)² - 1

=2(9) - 1

= 17

Therefore, (2, 17)
