Answer:
± 7
Step-by-step explanation:
Given
d =
, then
d = 7 or - 7, that is ± 7
Since 7 × 7 = 49 and - 7 × - 7 = 49
Simply cancel the common factor of 5 to get...

Therefore our final answer is.
Answer:
t =5 13/20
Step-by-step explanation:
t + 3/5 = 6 1/4
Subtract 3/5 from each side
t + 3/5 - 3/5 = 6 1/4 - 3/5
t = 6 1/4 - 3/5
Get a common denominator of 20
t = 6 1/4 *5/5 - 3/5 *4/4
t = 6 5/20 - 12/20
Borrow 20/20 from the 6
t = 5 + 20/20 +5/20 - 12/20
t = 5 25/20 - 12/20
t =5 13/20

Answer:
252m^3
Step-by-step explanation:
A solid having a triangular base is what we call a triangular prism. For every prism, its volume is always equal to the area of its base times its height. In other words:
V = AxH
V - volume
A- area
H - height of prism
We know that:
h = 4 m (side of base)
b = 14 (other base side)
A = bh/2 = 14x4/2 = 28 m^2
And then: V = A x H = 28 x 9 = 252 m^3
