3(s-5)/4 -3 = 4s- (s-3)/2pls answer fast​

Mathematics
1 answer:
Jobisdone [24]3 years ago
5 0

Answer:

s =  \frac{9± \sqrt{ - 39} }{4}

Step-by-step explanation:

\frac{3(s - 5)}{4 - 3}  =  \frac{4s \times (s - 3)}{2}

➡️ \frac{3(s - 5)}{1}  = 2s \times (s - 3)

➡️ 3s - 15 = 2 {s}^{2}  - 6s

➡️ 3s - 15  -  2 {s}^{2}  + 6s = 0

➡️ 9s - 15 - 2 {s}^{2}  = 0

➡️ - 2 {s}^{2}  + 9s - 15 = 0

➡️ 2 {s}^{2}  - 9s + 15 = 0

➡️ s =  \frac{ - ( - 9)± \sqrt{( - 9 {)}^{2}  - 4 \times 2 \times 15} }{2 \times 2}

➡️ s =  \frac{9± \sqrt{81 - 120} }{4}

➡️ s =  \frac{9± \sqrt{ - 39} }{4}

➡️ s∉ℝ

Evaluate 2 sin 60° + tan 45° + cos²60°​
DerKrebs [107]

Answer:

1.25+√3 or 2.9821 to the nearest ten thousandth.

Step-by-step explanation:

sin 60 = √3/2,  tan 45 = 1 and cos^2 60 = (1/2)^2 = 1/4

So we get 2 *√3/2 + 1 + 1/4

= √3 +  1.25

Can someone please help me with this multiple choice question?
iVinArrow [24]
1) the small and large triangles are similar, then we can write:

x/24 = 8/18
Cross multiplication → 18x = 24.8 → 18x = 192 and x = 192/18

and x = 32/3 Or 10 ²/³

2) Δ ABC is similar to Δ EDC Since:

∠A = ∠D = 90°

∠C is common
