the have identical length so to know the length of each pipe you should divide 22.4 by 7
22.4 / 7 = 3.2
Answer:
94cm²
Step-by-step explanation:
S = 2(lw + lh + wh)
=2(20+15+12)
=40+30+24
=94cm²
Hope this helps! Can u give me brainliest, please:)
Answer:
[2] Translation
[4]Transformation
Step-by-step explanation:
Translation is just moving the shape.
Transformation is changing the shape and tilting it changed the shape.
1) Correct.
2) The y-intercept is when x=0, so it is (0,5).
Answer:
The given equation is -2x^2 = -8x + 8
This can be rewritten as 2x^2 - 8x + 8 = 0
Here the value of a =2, b = -8 and c = 8
Discriminant = b^2 - 4ac
Now plug in the above values in the discriminant, we get
= (-8)^2 - 4*2*8
= 64 - 64
= 0
Here the discriminant is 0, so we will get one real root.
The discriminant is equal to 0, which means the equation has one real number solution.
Hope this will helpful.
Thank you.
