Answer:
C
Step-by-step explanation:
related equation
-16t^2 + 32t + 20 = 0
-4t^2 + 8t + 5 = 0
Δ/4 = 16 + 20 = 36
t1 = (-4 + 6)/-4 = -1/2
t2 = (-4 - 6)/-4 = 5/2
-16(t+1/2)(t-5/2)
-16(2t+1/2)(2t-5/2)
-4(2t+1)(2t-5)
Let
x------------><span>Sean vegetable plants
</span>y------------>Liz vegetable plants
z------------>Sejuan vegetable plants
we know that
y=3
z=2
x=3(y+z)--------> 3(3+2)=15
the answer part A) is
Sean has 15 vegetable plants
part B
This is an example of a part-whole problem.----------> true
<span>This is an example of a comparison problem.-------> true
</span>Addition then multiplication can be used to solve the problem.------> true
Answer:
The worksheet is 8 inches long
Step-by-step explanation:
Here, we want to get the length of the worksheet
From the description, we can see that the worksheet is rectangular in shape
Thus;
P = 2(l + b)
28 = 2(l + 6)
28/2 = l + 6
14 = l + 6
l = 14-6
l = 8 inches
The last one is the answer.......
