Find the scale of the known sides:
RT is similar to UW
5.4 /9 = 0.6
The smaller triangle is 0.6 times the larger one.
Multiply the length of RS to find UV:
6 x 0.6 = 3.6
The answer is A. 3.6 inches.
Answer:
4ft
Step-by-step explanation:
to get the area of a square you multiply the sides together so you just find the square root of the area
The answer is 16/10 = 40/25
You divided 16 by 40 to see what you need to multiply 16 to get 40. When I did that I got 2.5. So I did that to the 10 and got 25 minutes. Hope this makes sense
The numbers 7, 11, 12, 13, 14, 18, 21, 23, 27, and 29 are written on separate cards, and the cards are placed on a table with th
Sophie [7]
there are a total of 10 cards
there are 3 cards with even numbers
so you have a 3/10 probability of picking an even n umber
Answer:
-7 or 4
Step-by-step explanation:
use foil to get the quadratic equation:
x^2+5x-2x-10=18
x^2+3x-10=18
bring "18" to the left:
x^2+3x-10-18
x^2+3x-28
so what*what= -28
and
what+what=3
factors of -28: -7,4 -4,7 14,-2 -14,2 -28,1 -1,28
factors whose sum is 3: 7,-4
so substitute "7,-4" in place of 3:
x^2+7x-4x-28
2) split it in two groups
group 1) x^2+7x
group 2) -4x-28
x^2+7x has a GCF of "x"
x(x+7)
group 2) -4x-28 has a gcf of "-4"
-4(x+7)
3) (x-4) (x+7)=0
x-4=0
x=4
x+7=0
x=-7
x=4,-7
Hope this helps!
