Answer:
A. (x−2y)(y−3x)
=(x+−2y)(y+−3x)
=(x)(y)+(x)(−3x)+(−2y)(y)+(−2y)(−3x)
=xy−3x2−2y2+6xy
=−3x2+7xy−2y2
B. (2p+3)(p2−4p−7)
=(2p+3)(p2+−4p+−7)
=(2p)(p2)+(2p)(−4p)+(2p)(−7)+(3)(p2)+(3)(−4p)+(3)(−7)
=2p3−8p2−14p+3p2−12p−21

Answer: C 4
Step-by-step explanation:
are they functions? if not why?
Answer:
1 is yes, 2 is no because 1 and 3 repeat, which means that 2 Y-Values would get the x-value of 1 and 3, and x cannot have 2 different values.

What is the surface area of the regular pyramid given below?
A. 280 units2
B. 329 units2
C. 189 units2
D. 140 units2
The surface area of the regular pyramid in the diagram is 189 units². The correct option is C. 189 units²
Area of a PyramidFrom the question, we are to calculate the surface area of the regular pyramid
The surface area of the pyramid = Sum of area of the triangular faces + Area of the square base
∴ Surface area of the pyramid = [tex]4(\frac{1}{2}bh)+ b^{2}[/tex]
Surface area of the pyramid = 2bh + b²
Where b is the base
and h is the perpendicular height of each triangular faces
In the given diagram,
b = 7
h = 10
∴ Surface area of the pyramid = 2×7×10 + 7²
Surface area of the pyramid = 140 + 49
Surface area of the pyramid = 189 units²
Hence, the surface area of the regular pyramid in the diagram is 189 units². The correct option is C. 189 units²

Based on the following rule for translations, how will the preimage translate to get the image? (x,y) = (x, y - 3) *
What is x or solve for x
Answer:
x = 8
Step-by-step explanation:
The measure of an arc is equal to the angle at the centre subtended by the arc.
The sum of the 3 arcs = 180° , then
5x + 6 + 83 + 51 = 180
5x + 140 = 180 ( subtract 140 from both sides )
5x = 40 ( divide both sides by 5 )
x = 8
A customer in a store had two 50% off coupons. She tried to buy a purse with them, gave them to the cashier
and explained that the two 50% off coupons should mean that she gets the purse for free. The cashier
disagreed and refused to give the purse for free. What discount should two 50% off coupons actually give at the
store?
Answer:
Well, I think that the 50% coupons would give you only 50% off of your entire purchace. Not 100% off.

Answer:
[tex]\boxed{\tt x=58^{\circ}}[/tex]
Step-by-step explanation:
From the given diagram, we see that ∠YOZ and ∠XOY are complementary angles.
Complementary angles: two angles with measures that add up to 90°.
[tex]\tt m\angle XOY+m\angle YOZ=90^{\circ}[/tex]
[tex]\tt \angle XOY+\angle YOZ=90^{\circ}[/tex]
[tex]\tt 32^{\circ}+x=90[/tex]
Subtract 32 from both sides:
[tex]\tt 32^{\circ}+x-32^{\circ}=90^{\circ}-32^{\circ}[/tex]
[tex]\tt x=58^{\circ}[/tex]

Answer:
x=3
Step-by-step explanation:
You should add 75$ to 160$ and get $235, then divide 760 by 235. you an only go 3 days, because if you go another that's over the budget
