I need help resolving this please. 8=4(q-2)+4

1 answer:

7 0

8=4(q−2)+4
Step 1: Simplify both sides of the equation.
8=4(q−2)+4
8=(4)(q)+(4)(−2)+4(Distribute)
8=4q+−8+4
8=(4q)+(−8+4)(Combine Like Terms)
8=4q+−4
8=4q−4
Step 2: Flip the equation.
4q−4=8
Step 3: Add 4 to both sides.
4q−4+4=8+4
4q=12
Step 4: Divide both sides by 4.
4q/4=12/4
q=3
Answer:
q=3

Find the surface area of the composite figure

nataly862011 [7]

solution given:

For Cuboid

length[l]=11mm

breadth [b]=9mm

height[h]=6mm

For semi cylinder

height[H]=11mm

radius[r]= $\frac{9}{2}=4.5mm$

Now

Totalsurface area=2(lb+bh+lh)+½(2πr(r+H))-l*b[/tex]

:2(11*9+9*6+11*6)+22/7*4.5(4.5+11)-11*9

:438+219.2-99

:558.2mm²

Here area of base is subtracted as it is not included.

Total surface area of composite figure is :558.2mm².

Help is needed please help

Anna007 [38]

You have to do Pythagorean theorem:

$a^{2} +b^{2} = c^{2}$

"a" and "b" are the legs. In this case 7 is a leg and x is a leg

"c" is the hypotenuses, which is 19 here

so...

a = 7

b = x

c = 19

Plug the numbers above into the equation:

$7^{2} + x^{2} = 19^{2}$

$49 +x^{2} = 361$

Isolate x by subtracting 49 to both sides:

$(49-49) + x^{2} = 361 - 49$

$x^{2} = 312$

To solve for x you have to take the square root to both sides of the equation:

$\sqrt{x^{2} } = \sqrt{312}$

x = 17.6635

x = 17.7

Hope this helped!

Please help me please

Phoenix [80]

Answer:

x = 36

Step-by-step explanation:

The angles 3x - y and 2x + y form a straight angle and are supplementary, so

3x - y + 2x + y = 180

5x = 180 ( divide both sides by 5 )

x = 36

-----------------------------------------------

5y and 3x - y are vertical angles and congruent, hence

5y = 3x - y ( add y to both sides )

6y = 3x ← substitute x = 36

6y = 3 × 36 = 108 ( divide both sides by 6 )

y = 18
