I’m guessing angle 7 and 8 are equal
and if so the following is true
2x+15=3x
x=15
otherwise, please include more details of the problem, which is necessary if you want your problem to be solved fast and correctly.
Answer:
Triangle Area = 99.4 yds squared
Trapezoid Area = 57.5 cm squared
Step-by-step explanation:
area = a × b
/2
= 7.1 × 14
/2
= 49.7 (for the RAT)
= 49.7 x 2
= 99.4 yd squared
Any number can above 451 can be greater than it. Ok so now a number greater than 451 is : 548 Also if you have already learned about decimals, you could use a decimal.(If you haven't learned about decimals yet you could surprise your teacher with a decimal) The decimal you could use is 462.5 It is read four hundred sixty two and five tenths. Hope this helped

Step-by-step explanation:
Answer: The width is 7 meters. The length is 10 meters.
Step-by-step explanation: Area = Length × width
Length is 2w - 4
Substitute that value for length, then solve for w.
70 = w(2w - 4)
70 = 2w² - 4w reorganize to quadratic equation form
2w² - 4w -70 = 0 These are All even numbers; factor out 2 (divide all by 2)
w² - 2w - 35 = 0 factor this
(w - 7)(w + 5) set each factor = 0 and calculate the value of w.
w+5=0 w= -5 (disregard this one because dimensions of real rectangles can't be negative)
w - 7 = 0 w = 7 <u>The width is 7</u>
Substitute into the original expressions to get the value of Length.
2(7) -4 = L 14 - 4 = L The<u> Length is 10.</u>
Check by substituting into the original equation:
w × 2w -4 = 70
7 × 2(7) -4 = 70
7 × 10 = 70 TRUE!
w
