(1)

Triangular Prism

Given that:

  • Base (b) = 7 ft
  • Height (h) = 6 ft
  • Hypotenuse (y) = 9 ft
  • Depth (d) = 10 ft

Find the surface area!

Surface area =

bh + d(b+2y) =

(7 × 6) + (10×(7+(2×9))) =

42 + 250 =

<h3>292 sq ft ✅</h3>

Surface area =

2LW + 2LH + 2WH =

(2×(11×10)) + (2×(11×3)) + (2×(10×3)) =

220 + 66 + 60 =

2.25k - 20 = 6.5k + 14 please help me solve this step by step asap!
Rom4ik [11]
Answer:

k= -8

Explaining:


Move variable to the left-hand side and change its sign.

2.25k - 6.5k - 20= 6.5k - 6.5k + 14


Since two opposites add up to zero, remove them from the expression.

2.25k - 6.5k - 20= 14

Collect like terms!

-4.25k = 14 + 20

Add the numbers

-4.25k = 35


Divide both sides of the equation by -4.25

So you will get the answer: k= -8
