Answer:

Flase

Step-by-step explanation:

Solid a has a surface area of 170 sq ft.

Solid b has a surface area of 126 sq ft.

Just knowing this information we already know that the statement is false

Answer:

False

Step-by-step explanation:

1. Find the surface area

Shape 1 Shape 2

(4 x 5)2 + (5x5)4 = 140 (6 x 3)2 + (3 x 5)2 + (6 x 5)2 = 126

2. Exclude the bases

Shape 1 Shape 2

140 - 40 = 100 126 - 36 = 90

All in all, this is FALSE

Hope this helped. Please give brainliest. It took me a long time (30 minutes).

Answer:

$AC = 28$

Step-by-step explanation:

Given

$AB = 16$

$BC = 12$

Required

Determine AC

Since A, B and C are collinear, then:

$AC = AB + BC$

So, we have:

$AC = 16 + 12$

$AC = 28$

Yo please help

Alex Ar [27]

Answer:

Options 1, 3 and 4 are true

Step-by-step explanation:

The legs EF and DF of the right triangle DEF have lengths of 24 units and 7 units, respectively. By the Pythagorean theorem,

$DE^2=EF^2+DF^2\\ \\DE^2=24^2+7^2\\ \\DE^2=576+49\\ \\DE^2=625\\ \\DE=25\ units$

Find trigonometric functions:

$\sin \angle D=\dfrac{\text{Opposite leg}}{\text{Hypotenuse}}=\dfrac{EF}{DE}=\dfrac{24}{25}$

$\cos \angle E=\dfrac{\text{Adjacent leg}}{\text{Hypotenuse}}=\dfrac{EF}{DE}=\dfrac{24}{25}$

$\tan \angle D=\dfrac{\text{Opposite leg}}{\text{Adjacent leg}}=\dfrac{EF}{DF}=\dfrac{24}{7}$

$\sin \angle E=\dfrac{\text{Opposite leg}}{\text{Hypotenuse}}=\dfrac{DF}{DE}=\dfrac{7}{25}$

Thus, options 1, 3 and 4 are true

X^2-12x+12=0 completing the square

Makovka662 [10]

Answer:

x1 = 6 + 2√6 or x2 = 6 - 2√6

Step-by-step explanation:

x² - 12x + 12 = 0

We need to use formula:

a² - 2ab + b² = (a - b)².

x² - 12x = - 12

x² - 2*6x + 6²- 6² = - 12

(x - 6)² - 36 = -12

(x - 6)² = - 12 + 36

(x -6)² = 24

(x - 6) = √24 or (x-6) = -√24

(x - 6) = 2√6 or (x-6) = - 2√6

x = 6 + 2√6 or x = 6 - 2√6
