Answer:
76cm²
Step-by-step explanation:
SA=2lw+2lh+2hw
length=4cm
width=2cm
height=5cm
= 2(4×2+4×5+5×2)
=8+20+10
=2×38
=76cm²
I need an answer for this
Answer:
Step-by-step explanation:
18+12+9
Answer:
756 cm^2
Step-by-step explanation:
9 x 12 = 108 triangles
9 x 18 = 162 back side
9^2 + 12^2 = c^2
9^2 + 12^2 = 225
9^2 + 12^2 = 15^2
length of the hypotenuse is 15 so
15 x 18 = 270 slanted top
18 x 12 = 216 bottom
216 + 270 + 162 + 108 = 756 cm^2

Find the value of x
Answer:
x = 121
Step-by-step explanation:
Let the measure of the altitude of the given triangle be h units.
By geometric mean theorem:
[tex]h = \sqrt{23 \times x} \\ \\ h = \sqrt{23x} \\ \\ now \: by \: pythagors \: theorem \\ \\ {(x + 11)}^{2} = {h}^{2} + {x}^{2} \\ \\ \cancel{{x}^{2}} + 22x + 121 = {( \sqrt{23x} )}^{2} + \cancel{{x}^{2}} \\ \\ 22x + 121 = 23x \\ \\ 22x - 23x = - 121 \\ \\ - x = - 121 \\ \\ x = 121[/tex]
Find x of the angles are supplementary 3x-2 and 41 degrees ?
Answer:
x = 47
Step-by-step explanation:
3x - 2 + 41 = 180 {Supplementary}
3x + 39 = 180
3x = 180 - 39
3x = 141
x = 141/3
x = 47

Use the Distributive Property to simplify the expression.
1(8+x+4) = 0
Answer:
x + 12 = 0
Step-by-step explanation:
Answer:
x = -12
Step-by-step explanation:
1 x 8 = 8
1 x x = 1x
1 x 4 = 4
rewrite expression
8 + 1x + 4 = 0
combine like terms
8 + 4 = 12
1x + 12 = 0
subtract 12 from both sides
12 - 12 = 0
0 - 12 = -12
1x = -12
divide by 1 on both sides to get x by itself
1x/1 = x
-12/1 = -12

Hii! If someone could plz help me!
is -4.5 greater or less than 3?
Is -12/5 greater or less than 2?
From least to greatest order these: -3/2, -1, 11/4, 2, -3, 5.2, 0, 5.
(Btw I’m sorta new here so I apologize if I mess up)
Answer:
-4.5 is less than 3
-12/5 is less than 2
-3, -1.5, -1, 0, 2, 2.75, 5, 5.2
-3/2 = -1.5
11/4 = 2.75
Write the equation in slope intercept form
Solve the following equation. Write your answer in simplest form,
2/5x+4= 16
Answer:
x=30
Step-by-step explanation:
Answer:
x=30
Step-by-step explanation:
2/5x+4=16
First: subtract 4 from both sides, 2/5x=12
Second: multiply by 5 on each side, (it cancels out the fraction) to get 2x=60
Third: divide by 2 on both sides, x=30
