A square area=legnth times width
but for a square, legnth=width so
area=legnth^2
are=49
49=legnth^2
square root of both sides
7=legnth
the answer is 7
Answer:
A (x+3)−1=8open paren x plus 3 close paren minus 1 is equal to 8
C 2(x+3)=182 times open paren x plus 3 close paren is equal to 18
E 2x=122 x is equal to 12
Step-by-step explanation:
Given:
2(x+3) − 2 = 16
2x + 6 - 2 = 16
2x = 16 - 6 + 2
2x = 12
x = 12/2
x = 6
A. (x+3)−1=8
x + 3 - 1 = 8
x = 8 - 3 + 1
x = 6
B (x+3)−2=8
x + 3 - 2 = 8
x = 8 - 3 + 2
x = 7
C 2(x+3)=18
2x + 6 = 18
2x = 18 - 6
2x = 12
x = 12/2
x = 6
D x+3=9x
3 = 9x - x
3 = 8x
x = 3/8
E 2x=12
x = 12/2
x = 6
F 2x=15
x = 15/2
x = 7 1/2
Answer:
The number of blocks in one hour is the same that the unit rate, so 16 blocks per hour
Step-by-step explanation:
we know that
To find out the unit rate, divide the total blocks by the total time
so

Answer:
40
Step-by-step explanation:
So far, the Lengths we have are
4, 4, 8, and 4
for the bottom length, add 8 and 4
For the side length, and 4 and 4
so the lenghts are 4, 4, 8, 4, 8, and 12
4+4+8+4+8+12=40
