Answer:
x=2/3
Step-by-step explanation:
Since this is a rhomb, AD divides angle CDE in 2 equal parts: CDA=EDA.
Or 9x+3=6x+5
3x=2, x=2/3
Answer: Zoey needs 168 square feet if carpet squares.
Step-by-step explanation:
Zoey wants to cover her bedroom floor with carpet squares. Each square has an area of 1 square foot.
The formula for determining the area of a rectangle is expressed as
Area = length × width
Her bedroom measures 12 feet by 14 feet. Therefore, the area of her bedroom would be
12 × 14 = 168 square feet.
Therefore, the number of carpet squares that Zoey needs would be
168/1 = 168 square feet
<span>If you have the equation
</span>x2<span> + 2x - 3 = 0
</span><span>You can factor the quadratic to get
</span><span>(x - 1)(x + 3) = 0
</span><span>and hence the roots
</span><span>x = 1 and x = -3
</span>
<span>Conversely, if you have the roots x = 1 and x = -3 you can recover the quadratic equation by forming (x - 1)(x + 3) = 0.
</span>
<span>(x - 5 - 3i)(x - 5 + 3i) = 0
</span><span>which simplifies to
</span>x2<span> - 10x + 34 = 0

Answer: t= 0.866
Step-by-step explanation:
Formula to find t-test statistic :
where, n= sample size
= sample mean
= Population mean
=sample standard deviation
Given : Null hypothesis : H0:μ=8.000 cm
Alternative hypothesis : H1:μ<8.000 cm , since alternative hypothesis is one-tailed , so the test is one-tailed test.
Then , the t‑statistic for this test will be :-
Hence, the value of the t‑statistic for this test : t= 0.866
