Step-by-step explanation:
Answer:
Lateral Area = 176 cm²
Step-by-step explanation:
The prism is a rectangular prism
Formula for Lateral Area of the rectangular prism = 2(l + b)*h
Where,
Length (l) = 4 cm
Breadth (b) = 4 cm
Height (h) = 11 cm
Plug in the values
Lateral Area = 2(4 + 4)*11
= 2(8)*11
= 16*11
= 176 cm²
Answer:
68°
Step-by-step explanation:
As BA⊥BD, so ∠ABD = 90°
also, ∠ABD = ∠CBD + ∠ABC
⇒ 90° = 4x + 52° + 8x - 10°
⇒ 12x = 48°
⇒ x = 4°
now,
∠CBD = 4x + 52°
= 4(4°) + 52°
= 68°

Answer:
x = -1, 1, -5 , 5.
Step-by-step explanation:
x4 – 26x2 + 25 = 0
Factoring:
(x^2 - 25)(x^2 - 1) = 0
So x^2 - 25 = 0 gives x^2 = 25 and x = +/- 5.
x^2 - 1 gives x^2 = 1 and x = +/- 1.
