here's half of them:

1: 15 - (3r) = 6

2: q + 4f = 29

3: n^{2} + 12 = p/4

4: 0.5j - 5 = k + 13

for the rest, just know that:

sum means addition

Simplify (2√5 + 3√7)^2. PLEASE SHOW WORK<br><br><br><br> HELP
vagabundo [1.1K]
First you want to find 2√5+3√7, which is ≈12.40938989. Then you would square that number and you would get ≈153.9929574 rounding to the nearest number you would get ≈154.

So the answer is ≈154.

HELP! I am REALLY struggling!
soldier1979 [14.2K]
16 = 1/4x + 2.5...where x stands for diameter of large gear
16 - 2.5 = 1/4x
13.5 = 1/4x....multiply both sides by 4, eliminating the 1/4 on the right side
13.5 * 4 = x
54 = x.....the large gear is 54 cm

What is the height of the triangular prism below if the volume equals 1,638 cubic millimeters? 65 mm 63 mm 26 mm 28 mm.
sergejj [24]

Answer:

The height of the triangular prism is 26\ mm

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The volume of the triangular prism is equal to

V=Bh

where

B is the area of the triangular base

h is the height of the prism

<em>Find the area of the base B</em>

B=\frac{1}{2}(7)(18)=63\ mm^{2}

we have

V=1,638\ mm^{3}

h=x\ mm

substitute and solve for x

1,638=(63)x

x=1,638/(63)=26\ mm

What are the missing side lengths for the triangle?
ser-zykov [4K]

Answer:

BC=5\sqrt{2}, AC=5\sqrt{4}

Step-by-step explanation:

In a 45-45-90 relation triangle the two shortest sides will have equal length, meaning:

BC=5\sqrt{2}

To find the hypotenuse we must multiply the shortest side by \sqrt{2}, both sides are equal so it doesn't matter which we multiply.

AC=5\sqrt{2} \sqrt{2} \\AC=5\sqrt{4}
