Show that the triangles are similar by comparing the ratios of the corresponding sides. Simplify your answer completely in order

kirill [66]

Answer/Step-by-step explanation:

AC = 1.2

AB = 4

BC = 2.6

DF = 3

DE = 10

EF = 6.5

Thus:

$\frac{DE}{AB} = \frac{10}{4} = \frac{5}{2}$

$\frac{DF}{AC} = \frac{3}{1.2} = \frac{3*10}{1.2*10} = \frac{30}{12} = \frac{5}{2}$

$\frac{EF}{BC} = \frac{6.5}{2.6} = \frac{6.5*10}{2.6*10} = \frac{65}{26} = \frac{5}{2}$

The ratio of their corresponding sides are all equal to ⁵/2. Therefore, both triangles are similar.

Two variable quantities A and B are found to be related by the equation A^3 + B^3 = 9. What is the rate of change dA/dt at the m

Amanda [17]

3A^2 dA/dt + 3B^2 dB/dt = 0

If A=2, then 8+B^3=9, B=1

12 dA/dt + 9 = 0

dA/dt = -3/4

Help me plz

irakobra [83]

Answer:

I could do 1 and 3

1) 2x-3y=-2 ....1

2x+y=14......2

=-4y=-16

y=4

Substitute (y=4) into equation 1

2x-3 (4)=-2

2x-12=-2

2x=-2+12

2x=10

×=5

3) 5x+5y=20....1

-3x+5y=4......2

=8x=16

x=2

Substitute (x=2) into equation 1

5 (2)+5y=20

10+5y=20

5y=20-10

5y=10

y=2

3 (x+4) + 7x combining like terms

Debora [2.8K]

Answer:

$10x+12$

Step-by-step explanation:

we have

$3(x+4)+7x$

step 1

Apply distributive property

$3(x+4)+7x=3(x)+3(4)+7x$

$3(x)+3(4)+7x=3x+12+7x$

step 2

Combine like term

$3x+12+7x=(3x+7x)+12$

$(3x+7x)+12=10x+12$
