Base=x+7 Height=x Area=60. 60=((x+7)(x))/2----->60=(x^2+7x)/2
120=x^2+7x X^2+7X-120=0. QUDRATIC FORMULA: -7+/- SQRT(49+480)/2
(-7+/-23)/2... 8 and -15. -15 ISNT the answer because you cant have a negative length. X=8 Base=8+7---->15 Height=8
Answer:
6in²
Step-by-step explanation:
Given that :
Base of right angle triangle = 3
Height of right angle triangle = 4
Area of a triangle = 1/2 * base * height
Area of triangle = 1/2 * 4 * 3
Area of triangle = 2 * 3
Area of triangle = 6in²
Factor the following:
3 x^2 + 27 x + 60
Factor 3 out of 3 x^2 + 27 x + 60:
3 (x^2 + 9 x + 20)
The factors of 20 that sum to 9 are 5 and 4. So, x^2 + 9 x + 20 = (x + 5) (x + 4):
Answer: 3 (x + 5) (x + 4)
Answer:
$ 1,200 per square foot
Step-by-step explanation:
If you divide 540,000 by 450 you will get 1,200.
