Solve for x given that <br><img src="https://tex.z-dn.net/?f=%20%7B64%7D%5E%7B2x%20-%201%7D%20%3D%20%20%7B32%7D%5E%7Bx%20%2B%201
marissa [1.9K]

Answer:

x = \frac{11}{7}

Step-by-step explanation:

note that 64 = 2^{6} and 32 = 2^{5} , thus

(2^{6}) ^{2x-1} = (2^{5}) ^{x+1} , that is

2^{6(2x-1)} = 2^{5(x+1)}

2^{12x-6} = 2^{5x+5}

Since the bases on both sides are equal, then equate the exponents

12x - 6 = 5x + 5 ( subtract 5x from both sides )

7x - 6 = 5 ( add 6 to both sides )

7x = 11 ( divide both sides by 7 )

x = \frac{11}{7}

NEED HELP ASAP PLEASE! BRAINLIEST TO RIGHT ANSWER! For two similar triangles ABC and DEF, the scale factor of ∆ABC to ∆DEF is 2
hram777 [196]

Answer:

Assuming the similarity is that BC scales to EF, answer is

D. 1.5BC

Step-by-step explanation:

Because the triangles are smilar, AB/BC = DE/EF

If AB = 2BC

then DE = 2EF

but also DE = 3BC

so 2EF = 3BC

EF = 1.5BC
