Step-by-step explanation:
-5(7m-2)
-5*7m-(-5)*-2
-35m+10
The expansion of an equivalent expression −5(7m−2) is -35m + 10.
What is a distributive property?Distributive property says that the sum of two or more addends multiplied by a number, gives the same answer as distributing the multiplier, multiplying each added separately, and adding the products together.
Given expression
−5(7m−2)
For expanding the expression, use distributive property
= -5 × 7m - (-5) × (-2)
= -35m + 5 × 2
= -35m + 10
Hence, The expansion of an equivalent expression −5(7m−2) is -35m + 10.

Answer:
Volume of cube = 512 inch³
Volume of sphere = 268 inch³ (Approx.)
Volume of empty space = 244 inch³
Step-by-step explanation:
Given:
Side length of cube = 8 inches
radius of sphere = 4 inches
Find:
Volume of cube
Volume of sphere
Volume of empty space
Computation:
Volume of cube = Side³
Volume of cube = 8³
Volume of cube = 512 inch³
Volume of sphere = (4/3)πr³
Volume of sphere = (4/3)(3.14)(4)³
Volume of sphere = 268 inch³ (Approx.)
Volume of empty space = Volume of cube - Volume of sphere
Volume of empty space = 512 - 268
Volume of empty space = 244 inch³

A pyramid with a slant height 4.6 in whose triangular base measures 8 in on each side.Each altitude of the base measures of 6.9 in
Answer:
82.8 in²
Step-by-step explanation:
The surface area a triangular based pyramid :
Base area + 1/2(perimeter * slant height)
Base = 8 inches ; Slant height = 4.6 inches ; altitude of base measure = 6.9 inches
Base area of triangle :
1/2 * base * height
1/2 * 8 * 6.9
4 * 6.9
Base area = 27.6 in²
The perimeter, P = sum of sides ; (s1 + s2 + s3
P = 8 + 8 + 8 = 24 in
Hence,
Surface area = 27.6 in² + 1/2(24*4.6)
Surface area = 27.6 in² + (12 * 4.6) in²
Surface area = (27.6 + 55.2)
Surface area = 82.8 in²

The product of four and a number, decreased by seven
Answer:
32
Step-by-step explanation:
As per what is given
- the product of 4 and a number decreased by 7 (4 times that number let us call it x, minus 7)
- equals 100, the equation formed equals 100
Form an equation;
4(x - 7) = 100
Solve using inverse operations;
4(x - 7) = 100
/4 /4
x - 7 = 25
+7 +7
x = 32

Answer:
-3/2
Step-by-step explanation:
Given the funtion
(2x+3)² - 6x+9 = 0
(2x+3)² = 6x + 9
Expand
4x²+12x+9 = 6x + 9
4x²+12x - 6x = 0
4x²+6x = 0
4x² = -6x
4x = -6
x = -6/4
x = -3/2
Hence the value of x is -3/2

Please help ASAP I need helppppoñ
please help! I need to solve kt algebraically and if you can show your work/explain how you got the answer that would help a ton because I need that to!
Step-by-step
=> 900=-100x+300
=> -100x+300=900
=> -100x=900–300
=> -100x=600 divide both side by -100
=> x=-6
You start with 900= -100x + 300
you want to get x by itself on a side of the equation
you can do this by adding -100x to both sides of the equation
this would make it look like 900 + 100x = -100x + 100x + 300
if you simplify, you get 900 + 100x = 300
then subtract 900 on both sides to get x by itself
you will end up with 100x = -600
you divide both sides by 100 to get x by itself and you will end up with
x = -6
if you have any questions ask me and ill answer :)
