Answer:

r = 26

Step-by-step explanation:

30r + –20 = 760

Add 20 to each side

30r + –20+20= 760 +20

30r = 780

Divide each side by 30

30r/30 = 780/30

r = 78/3

r= 26

Can someone solve this?
romanna [79]

Answer:

u=4

v=2√3

Step-by-step explanation:

The 30-60-90 triangle theorem states that the shortest side of a triangle is half of the hypotenuse, so 2*2=4. So, the hypotenuse, <em>u</em>, is 4.

The longest leg is √3 times greater than the shortest leg, so 2*√3=2√3. So, the longest leg, <em>v</em>, is 2√3.

erastova [34]
Area = L*W
Original Area = 12*14 = 168
Multiply the dimensions by 2 = 12*2 = 24 and 14*2 = 28
New Area = 24 *28 = 672

New Area divided by original area = 672/168 = 4

The garden will be 4 times bigger in area
