Answer:
63m^2
Step-by-step explanation:
Find the area of each base
2.5(10)= 25
1.5(10) = 15
2(10) = 20
Add them together
20 + 15 + 25 = 60
Now find the area of the triangles at each side
2(1.5)(1/2) = 1.5
Since there are two triangles, multiply the area by 2
1.5(2) = 3
Add the areas together
60 + 3 = 63
There's your answer
Answer:
x = - 3, x = 
Step-by-step explanation:
Given
4x² + 2x - 30 = 0 ( divide through by 2 )
2x² + x - 15 = 0
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 15 = - 30 and sum = + 1
The factors are + 6 and - 5
Use these factors to split the x- term
2x² + 6x - 5x - 15 = 0 ( factor the first/second and third/fourth terms )
2x(x + 3) - 5(x + 3) = 0 ← factor out (x + 3) from each term
(x + 3)(2x - 5) = 0
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
2x - 5 = 0 ⇒ 2x = 5 ⇒ x = 
Answer:
$30.00
Step-by-step explanation:
The original price of the sweater is $75.00. The new sale price is the original price of 100% less 60% of the original price. That means the sales price is 40% of the original price.
You can do this 2 ways:
1. $75 x 60% or .60 = $45
$75-45 = $30
or
2. $75 x 40% or .40 = $30
Answer:
x = 8 − 2√7
Explanation: Isolate the radical, then raise each side of the equation to the power of its index.
2.6 + 9.2 x 4 would equal, <u><em>39.4</em></u>
