Answer:

X=10

Step-by-step explanation:

The two triangles are similar since each triangle is the same shape of right triangle but different sizes. To find x, write a proportion between two equal ratios of side lengths.

Solve by cross multiplying.

28(3x) = 20(4x+2)

84x = 80x + 40

4x = 40

x=10

Answer:

x=10

Step-by-step explanation:

The two triangles are similar since each triangle is the same shape of right triangle but different sizes. To find x, write a proportion between two equal ratios of side lengths.

$\frac{28}{20}=\frac{4x+2}{3x}$

Solve by cross multiplying.

28(3x) = 20(4x+2)

84x = 80x + 40

4x = 40

x=10

Choose the point-slope form of the equation below that

PilotLPTM [1.2K]

Answer:

A) y-4=-1/2(x+6)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(0-4)/(2-(-6))

m=-4/(2+6)

m=-4/8

simplify

m=-1/2

y-y1=m(x-x1)

y-4=-1/2(x-(-6))

y-4=-1/2(x+6)

Which numbers are perfect squares? Check all that apply.

Andrew [12]

A perfect square is a number made by squaring a whole number.

Since

$1^2=1;$
$4^2=16;$
$10^2=100,$

numbers 1, 16, 100 are perfect squares. You cannot find such whole number n, that

$2=n^2;$
$18=n^2;$
$32=n^2;$
$44=n^2;$
$94=n^2,$

therefore, numbers 2, 18, 32, 44, 94 are not perfect squares.

Answer: 1, 16, 100.

Find (3.3 × 10^4) + (1.9 × 10^5)

scoundrel [369]

Answer:

$2.23 \times 10^{5}$

Step-by-step explanation:

We have to find the sum of two numbers following the steps as described in the question.

The question is in the form of fill in the blanks.

Now, the given sum is $(3.3 \times 10^{4} )+(1.9 \times 10^{5} )$

= $(3.3 \times 10^{4} )+(19 \times 10^{4} )$

= $(3.3+19) \times 10^{4}$

= $22.3 \times 10^{4}$

= $2.23 \times 10^{5}$ (Answer)
