11. The total area of a quilt is defined as the equation: A = x² + 13x + 36. Find the possible side

Luda [366]

Answer:

(x + 9)(x4)

Step-by-step explanation:

$A = {x}^{2} + 13x + 36 \\ \\ = {x}^{2} + 9x + 4x + 36 \\ \\ = x(x + 9) + 4(x + 9) \\ \\ = (x + 9)(x+4)$

So, the possible side

lengths of the quilt are (x + 9) and (x + 4) units.

Which expression is equivalent to (256x^16)^1/4<br> A.4x^2<br> B.4x^4<br> C. 64x^2<br> D. 64x^4

antiseptic1488 [7]

Given expression: $(256x^{16})^{1/4}$ .

$\mathrm{Apply\:exponent\:rule}:\quad \left(a\cdot \:b\right)^n=a^nb^n$

$=256^{\frac{1}{4}}\left(x^{16}\right)^{\frac{1}{4}}$

$256=4^4$

$256^{\frac{1}{4}}=\left(4^4\right)^{\frac{1}{4}}=4$

$\left(x^{16}\right)^{\frac{1}{4}}=x^{16\cdot \frac{1}{4}}=x^4$

$(256x^{16})^{1/4} =4x^4$

<h3>Therefore, correct option is B option : B.4x^4</h3>

Answer:

Angle B is 120°

Step-by-step explanation:

Since it's a supplementary angle (angles that add up to 180°) on top of the triangle, you would find ∠B by subtracting 180 by 60 and ∠B will be 120°. Hope this helps:)

-4.35

Advocard [28]

Answer:

The answer is -4.35

Step-by-step explanation:

3/8 = 0.375

x = 0.4

Now,

3/8x - 4.5

0.375 × 0.4 - 4.5

0.15 - 4.5 = -4.35

Thus, The answer is -4.35
