Answer:

look below

Step-by-step explanation:

i dont know what that +... thing is

but when youre adding the negatives youre really just adding that number so this is just

48+45+42+81+84

45+42 is 87

now we have

48 + 87 + 81 + 84

87 + 81 is 168

48 + 84 is 132

now we have

168 + 132 and that is exactly 300

again dont know what the ... is so cant help you there

Use the net to find the lateral area of the prism.<br><br> ___cm^2
prisoha [69]

Answer:

900\ cm^2

Step-by-step explanation:

We can notice that the the prism provided is a rectangular prism.

By definition, The lateral  area of a rectangular prism can be calculated by multiplying the  perimeter of its base by its height.

The height is:

height=15\ cm

Then, the perimeter of the base is:

Perimeter=17\ cm+17\ cm+13\ cm+13\ cm=60\ cm

Then the lateral area is:

LA=60\ cm*15\ cm\\\\LA=900\ cm^2

Area (circle)=π*r²
diameter=30 cm
radius=diameter/2=30 cm/2=15 cm

Area(pizza)=π*(15 cm)²=225π cm²≈706.86 cm².

solution: 706.86 cm²

the direction angle for vectors 135° the X component of the vector is -3 what is the Ywhat is what what is the Y component of th
blagie [28]
Well, the X component (assuming x is the horizontal) is equal to RCosZ

Where Z is the angle and R is the size of the resultant

Substitute into formula :

X component = RcosZ
-3 = Rcos135°
R = -3/cos135°
R = 4.24264...
R = 4.24 (2dp)

The vertical component (or Y component) is equal to RSinZ

Vertical component = RSinZ
= 4.24264... × Sin135°
= 3

The answer is 3

harkovskaia [24]

Answer:

Answer choice B

Step-by-step explanation:

When you factor the equation, 12 only has 6x2 to equal the -12x. This means that you'll factor it into (3x-6)(x-2). When you set either of these equal to 0, the x value is 2.
