<h3>Answer: one</h3>

Reason:

The SSS (side side side) congruence rule says that two triangles are congruent if we have three pairs of sides that are the same length. Any triangle you construct that has side lengths 15, 7, and 5 will be congruent to the original triangle by the SSS rule. You may have to translate, rotate or reflect the second triangle so that it lines up perfectly with the first triangle.

Alternatively, consider triangle ABC that is the given triangle. Let AB = 15, BC = 7, and AC = 5. Then consider another triangle DEF such that DE = 15, EF = 7, and DF = 5. It is possible to do a series of translations, rotations, or reflections such that we get triangle DEF to overlap triangle ABC perfectly.

Find a polynomial that describes the area of the lawn which kevin has to mow in his front yard 6x+5,4x-9

Likurg_2 [28]

Answer:

$Area=24x^2-34x-45$

Step-by-step explanation:

Length and width of the yard are $(6x+5)$ and $(4x-9)$ .

$Area=length\times width\\\\Area=(6x+5)\times (4x-9)\\\\Area=24x^2+20x-54x-45\\\\Area=24x^2-34x-45$

Aloiza [94]

Answer:

Part A)

$P=\$8,500\\ r=0.052\\n=4$

Part B) $S(7)=\$12,203.47$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$S(t)=P(1+\frac{r}{n})^{nt}$

where

S is the Future Value

P is the Present Value

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

Part A)

in this problem we have

$P=\$8,500\\ r=5.2\%=5.2/100=0.052\\n=4$

Part B) How much money will Marcus have in the account in 7 years?

we have

$t=7\ years\\ P=\$8,500\\ r=0.052\\n=4$

substitute in the formula above

$S(7)=8,500(1+\frac{0.052}{4})^{4*7}$

$S(7)=8,500(1.013)^{28}$

$S(7)=\$12,203.47$

Find the slope of the line below . Enter your answer as a fraction or decimal. Use a slash mark ( / ) as the fraction bar if nec

natali 33 [55]

Answer:

1/5

Step-by-step explanation:

We can find the slope of a line given two points by using the following

m = ( y2-y1)/(x2-x1)

= ( 3-0)/(7 - -8)

= ( 3-0)/(7+8)

= 3/15

= 1/5

What is the slope of a line that is parallel to the line y=3/4x+2

stepladder [879]

If two lines are parallel to one another, then their slopes are identical. The slope in the line above is 3/4. Therefore, a line parallel to that line will also have a slope of 3/4, it will just have a different y-intercept.
