Combine like terms to simplify the expression: 7x + 3y - 2 + 6x + 1 + y^2
a_sh-v [17]

The correct answer is B because after you simplifiy the expression, you would  get that answer:

7x + 3y - 2 + 6x + 1 + y^2

combine all the like terms to one side first

7x + 6x - 2 + 1 + y^2

then simplify

13x - 1 + y^2 or  y^2 + 3y + 13x - 1

Volume and Surface Area<br><br> Math help 100 points
kondor19780726 [428]
Part 1) we have that
volume smaller solid=512 cm³
volume larger solid=2197 cm³

we know that
volume larger solid=[scale factor]³*volume smaller solid
scale factor=∛[volume larger solid/volume smaller solid]
scale factor=∛[2197/512]-----> scale factor=1.625


Part 2) 
the ratio of the surface areas is equal to [scale factor]²
1.625²-------> 2.64

Part 3)
surface area smaller solid=960 cm²
then
surface area larger solid=scale factor²*surface area smaller solid
surface area larger solid=[1.625]²*960-----> 2535 cm²
 surface area larger solid is  2535 cm²

Guys!! anyone can help me solve this geometry problem?<br>What is the area of this triangle?
NeX [460]

Answer:

10657.5

Step-by-step explanation:

<h2>Long way that is unnecessarily long</h2>

We can start by finding the area of the larger triangle. Using the Pythagorean theorem, we can say that 251²-105²=the bottom side², and  251²-105²=51976, so the bottom side of the larger triangle is √51976 , or approximately 228. Then, the area of the larger triangle is √51976 * 105/2 = 11969 (approximately). Then, the area of the smallest triangle (the largest triangle - the one that we're trying to find the area of) is 105*(√51976-203)/2 = approximately 1312. Then, subtracting that from the total area, we get (√51976 * 105 -  105*(√51976-203))/2 = 105*203/2 = 10657.5

<h2>Short way</h2>

ALTERNATIVELY, upon further review, we can just see that the height is 105 and the base is 203, so we multiply those two and divide by 2, as is the formula for the area of a triangle, to get 10657.5

What is the exponential form of the following expression? (-5)(-5)(-5) . c . c .c
andrew-mc [135]

Answer:

(-5)^3 * c^3

Step-by-step explanation:

Given

(-5)(-5)(-5) * c * c * c

Required

The exponent form

We have:

(-5)(-5)(-5) * c * c * c

Apply the following law of indices;

x * x * x ...... = x^n

So, the expression becomes:

(-5)^3 * c^3
