Answer:

5x + 16 = 7x

2x = 16

x = 8

AC = 7x

BC = 15

AB = 5x + 1

AC = 7(8)

AC = 56

Find the length of the missing side. If necessary, round to the nearest tenth. 40 and 35

vivado [14]

Answer: 53.2

Step-by-step explanation:

Using pythagorean theorem, a^2 + b^2 = c^2

40^2 + 35^2 = sqrt of 2825

which is 53.15

rounded up to nearest tenth is 53.2

Based on the diagram, which expresses all possible lengths of segment AB?

lukranit [14]

we know that

The sum of the lengths of any two sides of a triangle is greater than the length of the third side (Triangle Inequality Theorem)

1) $AC+BC > AB$

$27+54 > AB\\ 81 > AB\\ AB < 81$

2) $27+AB > 54$

$AB > 54-27\\ AB > 27$

3) $54+AB > 27$

$AB > 27-54\\ AB > -27$

therefore

the answer is

$27 < AB < 81$

15 points Question

Mrac [35]

Answer:

18ft²

Step-by-step explanation:

V volume pyramid = 1/3× base area × height

V = 1/3 × B × h

24 ft³ = 1/3(12ft²)(6ft)

when V =54 ft³ h= 9ft B =?

V=1/3Bh

B=V3/h

B=(54×3)/9

B=6×3

B=18 ft²

I need help solving this for pre calc

Katarina [22]

Starting with:

$\frac{2p}{p+1} + \frac{3}{p-1} = \frac{15-p}{p^{2}-1}$

First, the difference of 2 squares shows that $p^{2} - 1 = (p+1)(p-1)$

Sub that in and multiply both sides by $(p-1)(p+1)$ :

$\frac{2p(p+1)(p-1)}{p+1} + \frac{3(p-1)(p+1)}{p-1} = \frac{(15-p)(p-1)(p+1)}{(p-1)(p+1)}$

This easily simplifies to $2p(p-1) + 3(p+1) = 15 - p$

See if you can continue from here. If not, leave a comment and I or someone else can show you the rest.
