Answer:

B. SAS

Step-by-step explanation:

Two sides of ∆DEF (DE and DF) are proportional to two corresponding sides of ∆ABC (AB and AC), and also their included angles (<D and <A) are equal to each other.

Therefore, based on the SAS criterion, both triangles are proven to be similar to each other.

Both triangles satisfy the SAD Criterion, and hence, they can be proven to be similar to each other.

The number of charter schools is 4 less than twice the number of alternative schools and there are 48 charter schools how many a

jarptica [38.1K]

Let x = the number of alternative schools.

Therefore, 2x - 4 = 48.
2x -4 +4 = 48 + 4
2x = 52
x = 26

Therefore, there are 26 alternative schools(You could check this answer by substituting x=26 into the equation above.).

cuboid of length 24cm and volume 768cm^3 the width and hight are not equal.give a pair of possible values for their length.

Brilliant_brown [7]

Answer:

Possible values of dimensions are (24,16,2) or (24,8,4)

Step-by-step explanation:

We are given the volume of the Cuboid and length . We are required to find the possible values of width and height from this information.

Let us say that the width is x and height is y

Length = 24

Volume of a cuboid = length * width * height

Volume = 768

768=24*x*y

$xy=\frac{768}{24}\\xy=32\\$

xy=32

Now the possible factors of 32

32=1*32 ( Which shall not be taken into consideration as length is already given as 24 and width or height can not be more length)

32=2*16

32=4*8

Hence the possible values width are 8, 16 and that of height 4 and 2

Hence the possible values of dimensions are (24,16,2) or (24,8,4)

Bobby biked 12/3 hours on monday 21/3 hours on tuesday and 22/3 hours on wednesday. what is the total number of hours bobby spen

serg [7]

The fractions you're given can be simplified down, so you get (12 ÷ 3) 4 hours on Monday, (21 ÷ 3) 7 hours on Tuesday, and (22 ÷ 3) 7 1/3 hours on Wednesday. You can now add these up and get your answer as 18 1/3 hours, or 18.33.

I hope this helps!

Solve the equation. identify any extraneous solutions. x=√6x+7

marshall27 [118]

In order to solve the equation we first need to put the condition:
6x+7>=0
x>= -7/6

We square the equation:
x^2=6x+7
x^2-6x-7=0
x^2+x-7x-7=0
x(x+1)-7(x+1)=0
(x-7)(x+1)=0
x1=7
x2=1

Both solutions meet the condition.
