Answer:
25 and 20 milies/gallons
Step-by-step explanation:
Let the fuell efficientcy of the first and the second car be f and s in gallons/miles.
Then the distance traveled by car 1 is 30 f and the car 2 is 25 s.
Since we also know that 1250 is the total distance traveled then
30 f + 25 s = 1250 (1)
Moreover we know that the efficiency is 45 miles/gallon. Hence
f + s = 45
Multiply by 30 we have
30 f + 30 s = 1350 (2)
Subtract the (1) equation from (2) we have
5s = 100
s = 20
f + 20 =45
f = 25
So the efficiency of the first car is 25 miles/gallons while the second one is 20 miles/gallons.

Find the area of trapezium whose parallel side are 10 and 12 cm. And height is 7 cm
Answer:
77 cm²
Step-by-step explanation:
We know that
Area of trapezium = ½ (a + b) × h
Area = ½ × (10 + 12) × 7
Area = ½ × 22 × 7
Area = 11 × 7
Area = 77 cm²
Length of parallel sides = 10 cm and 12 cm
Height = 7 cm
What To Find :Area of trapezium
Formula Using :[tex]\begin{gathered} {\underline{\boxed{ \rm {\red{Area \: of \: trapezium \: = \: \frac{1}{2} \: \times \: (a \: + \: b) \: \times \:Height }}}}}\end{gathered}[/tex]
Where ,
a and b is Parallel sides Solution :[tex] \begin{cases} \large\bf\purple{ \implies} \rm \:Area \: of \: trapezium \: = \: \frac{1}{2} \: \times \: (10 \: + \: 12) \: \times \:7 \\ \\ \large\bf\purple{ \implies} \rm \:Area \: of \: trapezium \: = \: \frac{1}{2} \: \times \: 22\: \times \:7 \\ \\ \large\bf\purple{ \implies} \rm \:Area \: of \: trapezium \: = \: \frac{1}{ \cancel2} \: \times \: \cancel{22} \: ^{11} \: \times \:7 \\ \\ \large\bf\purple{ \implies} \rm \:Area \: of \: trapezium \: = \:11 \: \times \: 7 \\ \\ \large\bf\purple{ \implies} \rm \:Area \: of \: trapezium \: = \:77 \: {cm}^{2} \end{cases}[/tex]

Step-by-step explanation:
What do you mean by Factoring Polynomial?
a. a technique that is based on the property
b. to express or expressing a polynomial as a product
c. breaking down a structure into its fundamental prime factors
d. expressing a product of two other natural numbers
Step-by-step explanation:
Factoring a polynomial is the process of decomposing a polynomial into a product of two or more polynomials. For example, f ( x ) = x 2 + 5 x + 6 f(x) = x^2 + 5x + 6

2x^2 has factors {2, x, x}
-12x has factors {-1, 2, 2, 3, x}
13 has factors {1, 13} (it is prime)
Coefficients: {2, -12, 13} . . . see note below
Constants: {13}

Additional comment
We have listed the prime factors of each term, any subset can be multiplied to be a factor of the term. For example, 2·3 = 6 is a factor of -12x.
Please note that some sources do not consider a constant (13) to be a coefficient. You will need to refer to your curriculum materials to see what your author says about that.

Solve for x.
-5x = -10
x = 2
x = -2
x = 50
Answer:
Putting x= 2
[tex]( - 5) \times 2 = - 10 \\ - 10 = - 10[/tex]
putting x = -2
[tex]( - 5) \times ( - 2) = - 10 \\ 5 \times 2 = - 10 \\ 10 = - 10 \\ this \: is \: not \: correct \: equation[/tex]
putting x = 50
[tex]( - 5) \times 50 = - 10 \\ - 250 = - 10 \\ this \: is \: also \: not \: correct \: equation[/tex]
so, x = 2 is applicable.
