Answer:
h=A/b
Step-by-step explanation:
Think of putting number in the place of the letter, for example
A is 4
b is 2
h is 2
4=2 x 2 then plug the numbers in the right spot
2=4/2 then see what can be rearranged or what is left to make the
equation true
Answer:
5, -1
Step-by-step explanation:
set the given equation equal to 0.
add 9 to both sides
take the square root of both sides and remove the exponent on left side.
x-2 = +3
x-2= -3
solve for x (for each equation)
x= 5, x= -1
Answer:
5
Step-by-step explanation:
25 - 40 + 1
Answer:
D
Step-by-step explanation:
If we use the calculator will find out that x= √151/2 ≈ 6.1441
D. 6 < x < 7
x is less then 7 and greater than 6
Without the calculator you can think that 151 is almost 144 that is 12² so
we can approximate √151 to be a bit more then 12
√151/2 = a bit more then 12 /2 = 6 and a bit more
this person is approximately 72.0472441 inches tall because 1 meter is 39.3701 inches.
